Question

the probability that a male will be colorblind is 3.8%. What is the probability that at least one out of a group of 54 men will be colorblind?

Answer 1

at least one
translate as "not none"

Answer 2

compute the probability that none are colorblind (that is easy) and subtract that number from one

Answer 3

im really not too good at probabilities :/ @satellite73

Answer 4

the probability any one is colorblind is \(.038\)
the probability they are not is therefore \(1-.038=0.962\)
the probability that all 54 are not is
\[(.962)^{54}\] and so the probability that at least one is is
\[1-(0.968)^{54}\]

Answer 5

.8273?

@satellite73

Answer 7

Answer 8

did you mean to put .968?

Answer 9

your answer is right

Answer 10

sweet thank you again!

Answer 11

oh wait hold on

Answer 12

was it supposed to be .962?

Answer 13

should be \(1-(0.962)^{54}\)

Answer 14
