Question

3.
A Kiddy bank contains hundred 50p coins, fifty 1 rupee coins, twenty 2 rupee coins and ten 5 rupee
coins. Ifit is equally likely that one of the coins will fall out when the bank is turned upside
down, what is the probability that the coin (i) will be a 50 p coin? (ii) will not be a 5 coin?
​

Answer 1

Answer:

(i)P(50p)=.555..

(ii)P(not 5)=•9444

Step-by-step explanation:

P(50p)=no of 50p coins÷total no of coins

=100÷180

=•5555

P(not 5)=1-P(5)

P(5)=10÷180

=•05555

P(not 5)= 1-•05555

=•94444
