Answer:


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)
