Kane used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. The results are shown in the tables below:
Using Kane's simulation, what is the probability of rolling a 2 on the number cube and the coin landing heads up?

I though i would subtract 2 from the total but guess not how it is .

- anonymous

would be 87/100

take a look at the table
what is the probability of rolling a 2?

- anonymous

32

- Vocaloid

not quite, remember that probability of rolling a 2 = (number of 2's/total number of rolls)

- Vocaloid

your answers should be a fraction

- anonymous

32/6

- Vocaloid

how many times was the die rolled?

- anonymous

5 1/3 or 5.33

- Vocaloid

I'll ask again, how many times was the number cube rolled?

- anonymous

6

- Vocaloid

please read the problem again
how many times was the number cube rolled?

- anonymous

100

- Vocaloid

right
so, the probability of rolling 2 = (number of 2's/total number of rolls) = ?

- anonymous

2/100?

- Vocaloid

how many times did 2 get rolled?

- anonymous

50

- Vocaloid

please read the table again
how many times did 2 get rolled?

- anonymous

32

- Vocaloid

right, so probability of rolling 2 = (number of 2 rolled/total number of rolls) = ?

- anonymous

2/32

- Vocaloid

not quite, let's try again...
how many times did 2 get rolled?

- anonymous

32

- Vocaloid

right, and how many total rolls were there?

- anonymous

100

- anonymous

32/100

- Vocaloid

yes! now let's move on to the next step of the problem

- Vocaloid

now, we need to find the probability of the coin landing heads up
probability of heads = (number of heads/total number of coin flips) = ?

- anonymous

55/6

- Vocaloid

how many times was the coin flipped?

- anonymous

100

- Vocaloid

right, so...
probability of heads = (number of heads/total number of coin flips) = ?

- anonymous

55/100

- Vocaloid

right, now we multiply the two probabilities together
(32/100)*(55/100) = ?

- anonymous

.176

- Vocaloid

great! that's it

- anonymous

i would convert to fraction

- Vocaloid

176/1000

- anonymous

thanks
