A piggy bank contains 82 nos. of 50-paise coins, 37 nos. of 1-rupee coins and 80 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?
From a deck of 52 cards 1 card is drawn at random. What is the probability that it will be a red Ace?
From a deck of 52 cards two cards are drawn at random. What is the probability that both one is a hearts, and the other a Spades?
Number of ways of drawing 2 cards out of 52 = 52C2 = $(52 × 51)/2$ = 1326. There are 13 hearts and 13 Spades in the deck. So 2 such cards can be drawn in 13 × 13 = 169 ways. The probability = 169/1326 = 13/102.
There are 40 students in Class X of a school of whom 25 are girls and 15 are boys. If one student is absent today, what is the probability that it is a girl?
