A piggy bank contains 73 nos. of 50-paise coins, 37 nos. of 1-rupee coins and 81 nos. of 2-rupee coins. The piggy bank is turned upside down, and one coin falls down. What is the probability that it is a 50-paise coin?
A box contains 70 red balls and an unknown number of blue balls. If the probability of drawing a blue ball is 5 times the probability of drawing a red ball, then how many blue balls are there in the box?
What is the probability of getting a sum less than 12 from two throws of a dice?
From a deck of 52 cards two cards are drawn at random. What is the probability that both one is a clubs, and the other a diamonds?
Number of ways of drawing 2 cards out of 52 = 52C2 = $(52 × 51)/2$ = 1326. There are 13 clubs and 13 diamonds in the deck. So 2 such cards can be drawn in 13 × 13 = 169 ways. The probability = 169/1326 = 13/102.
If P(E) = 0.56, then what is the probability of non-occurrence of E?
