Question

A piggy bank contains fifty 50 paise coins, fourty ` 1 coins, twenty ` 2 coins and twenty ` 5 coins. If it is equally likely that one of the coins will fall out when the bank is turned upside down, then what is the probability that the coin (i) Will be a 50 paise coin ? (ii) Will not be a ` 5 coin ?

Answer 1

Answer:

1. 5/13

2. 11/13

Step-by-step explanation:

1. probability = no of possible outcomes for a 50 paise coin/total no of outcomes

= 50/130

= 5/13

2. probability  = no of possible out comes for not a 5 coin (sum of all coins except 5 coin)/ total no of outcomes

= 110/130

= 11/13
