Question

pls answer the above probability question

Answer 1

Total possible outcome=100+50+20+10=180
(1) P(50p coin) =100/180 =5/9
(2) P(rs 5 coin) =10/180 =1/18
Hence P(not rs 5 coin) = 1 - 1/18 = 17/18

Answer 2

Total possible outcome = 100 + 50 + 20+10=180

P[50p coin] =100/180 = 5/9

P[ Rs 5 coin] =10/180 = 1/18

Hence P[Not Rs 5 coin] = 1 -/18 =17/18
