Answer:
Step-by-step explanation:
We have ,
No.of.50 p coins = 100
No.of. 1 rupee coins = 50

Answer:
Number of 50 paise coins = 100
Number of 1 rupee coins = 50
Number of 2 rupee coins = 20
Number of 5 rupee coins = 10
So, total number of coins = 100 + 50 + 20 + 10 = 180
(1) Probability of 50 paise coin = Number of 50 paise coins/total number of coins = 100/180 = 5/9
(2) Probability of not 5 rupee coin = 1 - Probability of 5 rupee coin
= 1 - Number of 5 rupee coins/total number of coins = 1 - 10/180 = 1 - 1/18 = 17/18
(3) The concept used here is probability.
(4) I could not interpret which value are you taking about. Kindly be a little specific so that we can provide you meaningful help.
