Answer 1

Given :-

Probability (p) = 65% = 0.65

Number of trails (n) = 10

Given parameter follows a Binomial distribution. So we can use Binomial distribution to find P(X$\geq$8).

Using Excel command.

P(X$\geq$8) = 1- P(X<8) = 1-P(X$\leq$7)

P(X$\geq$8) = =1-BINOMDIST(7,10,0.65,true) = 0.2616 =26.16%
