Answer:

a) 0.1091

b) 0.9994

c) 0.5886

Step-by-step explanation:

X = the number of fish out of 20 that die after 24 hours

x = 0, 1, 2, . . . , 20

X~ Binomial (n= 20, p =0.20)

P(14 survive) = P(X = 6)

= $nC_r p^r q^{n-r}= 20C_6 0.2^6\times0.8^{14}$ =0.1091

Similarly we can find out

P(at least 10 survive) = P( X <= 10 ) = (Using technology) = 0.9994

P(at most 16 will survive) = P(X <= 16) = (Using technology) = 0.5886

-2 = -(x-8)
-2 = -x + 8 ( - * + = - and - * - = + )

-2 - 8 = -x +8 - 8
-2 - 8 = -x
-(2+8) = - x
-10 = -x | * (-1)

x=10
