Please help? A gambler has developed a weighted sixsided die with sides marked 1, 2, 3, 4, 5, 6. The probability of rolling a 6 is 0.4 and all other sides are equally likely. (X is a random variable). What is the probability that an even number is rolled?

Best ResponseYou've already chosen the best response.0Yes I do, but what I am confused about is that he gave us an assigned probability. Usually the probability for rolling a dice is 1/6, but he made it .4 and that confuses me.

Best ResponseYou've already chosen the best response.1ok so you know that the probablilty of rolling two is 1/6 right

Best ResponseYou've already chosen the best response.1well it is confusing but what is your best guess

Best ResponseYou've already chosen the best response.1we know all of them have a probibility of 1/6 so what u do with the 0.4 is divide or multiply

Best ResponseYou've already chosen the best response.0I thought you said multiply. So wouldn't it be 0.4 x 1/6?

Best ResponseYou've already chosen the best response.1the * is the multivly sign

Best ResponseYou've already chosen the best response.1and the / is division

Best ResponseYou've already chosen the best response.1so after you multiply

Best ResponseYou've already chosen the best response.1and thats your answer 2.4 you get it

Best ResponseYou've already chosen the best response.0Where did the 6 come from though? I thought we were using 1/6. So wouldn't 0.4 x (1/6)= .0667?

Best ResponseYou've already chosen the best response.1but we have to multiply th ewhole number and then

Best ResponseYou've already chosen the best response.0I thought probability was supposed to be between 0 and 1

Best ResponseYou've already chosen the best response.1no its one through 6

Best ResponseYou've already chosen the best response.1so if yyou peice it all together 0.4x6=2.4 And that peices it all together

Best ResponseYou've already chosen the best response.2Soo basically what u have to know is when u add all the probabilities they should be equal to 1

Best ResponseYou've already chosen the best response.1yes they do 1/6+1/6 ect.

Best ResponseYou've already chosen the best response.1and youll get 1 once you add them all and thank you so much rushwer for your help

Best ResponseYou've already chosen the best response.2P1 = probability of rolling 1 P2 = probability of rolling 2 P3 = probability of rolling 3 P4= probability of rolling 4 P5= probability of rolling 5 P6 = Probability of rolling 6 P1+P2+P3+P4+P5+P6 = 1

Best ResponseYou've already chosen the best response.1yea thats what i meant too thats what i was trying to help him get in my equation

Best ResponseYou've already chosen the best response.2Except for P6 others are same right? so we can say P1=P2=P3=P4=P5 so instead of P1+P2+P3+P4+P5 we can right 5P1 right?

javalos01

Best ResponseYou've already chosen the best response.1So do you get it now

Rushwr

Best ResponseYou've already chosen the best response.2so 5P1 + P6 = 1 We know P6 = 0.4 So 5P1 = 10.4 = 0.6 So P1 = 0.6/5 = 0.12 Except for the probability of rolling 6 other probabilities are 0.12

Best ResponseYou've already chosen the best response.0But it says all other sides are equally likely. So that means the probability of rolling a 6 is 0.4. And the probability or rolling either a 1,2,3,4, or 5 is 0.4 as well?

Rushwr

Best ResponseYou've already chosen the best response.2That is ; P1= 0.12 P2 = 0.12 P3 =0.12 P4 = 0.12 P5 = 0.12 P6 = 0.4 Now add up the probabilities of the even numbers ! That is P2+P4+P6 Then u get the probability of rolling an even number

Best ResponseYou've already chosen the best response.0So all the other trials would have to be equal to 0.6 right? so 0.6/ 5= .12

Best ResponseYou've already chosen the best response.2"The probability of rolling a 6 is 0.4 and all other sides are equally likely" this what the question said. I think u took it wrong !!! This means probability of rolling 6 is 0.4 and all the others equal. But this doesn't mean all the other sides are equal to 0.4 . Simply it says the probability of rolling 6 is different than the others

Best ResponseYou've already chosen the best response.0I'm guessing I add all the probabilities together. P(2)= .12 P(4)=.12 P(6)= .4. Added together is this ..
