Question

1. What is the probability that a non-leap year selected at random will have 53 sundays. 2.In a lottery there are 10 prizes and 25 blanks. Find the probability of getting a prize.

Answer 1

1: Non leap year -365 days

52 weeks -364 days (extra days= 1) n(A) =1

p(A) =n (A)/n (S)

p(A) = 1 /7

2 total (s) = 10+25 = 35

n(p) prizes = 10

p(P) = n(P)/ n(S)

p(P) = 10/ 35

p(P)= 2 /7
