Question

a) A kiddy bank contains hundred 50 p. coins, fifty 1 coins. thirty *2 coins and twenty 75 coins. If it is equally likely that are of the coins will fall out when the bank is turned upside down then show that the probability of the coin (i) will be a 50p. coin (ii) will not be a 75 coin and (iii) will be either 1 coin (or) 7 2coin are 1/2 * 9/10 and 2/5 respectively​

Answer 1

Answer:

50 90 and 2/5

Step-by-step explanation:

ok number of coins = 100+50+30+20 = 200

number of 50 p coin = 100

probablity of getting a 50 p coin = 100/200 = 1/2 = 50%

probablity of not getting  75 coin = 180/200 = 90%

probablity of getting 1 or 2 coin = 50+30 = 80 = 80/200 = 2/5

hope it helps
