Question

Suppose that 0.10 of population is colourblind if 25of sample drown from this population find probability that at least 7 have coroblind

Answer 1

`P(X \geq 8)=22*10^(-4)`

Explanation:

From The Question we are told that

Prob that population is colourblind
`P(C)=0.10`

Sample size
`N=25`

Generally the equation for Number of color blinds is mathematically given by

`P(X \geq 8)=\sum^(25)_(x=8)(25..x)(0.10)^x(0.90)^25-x`

`P(X \geq 8)=22*10^(-4)`
