Answer:
Step-by-step explanation:
A purse contains Rs1 , Rs2 and Rs5 coins.
No.of Rs1 coin in purse=10
No.of Rs2 coin in purse=14
No.of Rs5 coin in purse=14
No.of Rs2 and Rs5 coin in purse=14+14=28
No.of Rs3 coin in purse=0
Total coins=38
(a)
P(E)=No.of favourable outcomes/total no.of outcomes
P(not Rs1 coin)= no.of Rs2 and Rs5 coins/total no.of coins
P(not Rs1 coin)=28/38
Hence P(not Rs 1 coin)=14/19
(b)
P(Rs3 coin)=no.of Rs3 coin/total no.of coins
P(Rs3 coin)=0/38
P(Rs3 coin)=0
Hence P(Rs3) coin=0
