Vinvika [58]

Answer:

p (X= 4) = 0.266

Explanation:

Probability of randomly selected baby elk to survive adulthood = 46%

As per binomial setting

p (X= k)  = \frac{n!}{k! * (n-k)!} p^k(1-p)^{n-k}

Substituting the given values, we get -

p (X= 4)  = \frac{8!}{4! * (8-4)!} 0.46^4(1-0.46)^{8-4}

p (X= 4)   =   \frac{8*7*6*5 *0.44775 * 0.0850306}{4*3*2*1}

p (X= 4) = 0.266
