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

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

not quite, remember that probability of rolling a 2 = (number of 2's/total number of rolls)
Vocaloid
  • Vocaloid
your answers should be a fraction

how many times was the die rolled?

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

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

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

2/100?

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

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

right, and how many total rolls were there?

yes! now let's move on to the next step of the problem
Vocaloid
  • 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) = ?

how many times was the coin flipped?

Vocaloid
  • Vocaloid
right, so... probability of heads = (number of heads/total number of coin flips) = ?
anonymous
  • anonymous
55/100
Vocaloid
  • Vocaloid
right, now we multiply the two probabilities together (32/100)*(55/100) = ?

.176

great! that's it

i would convert to fraction
