One card is drawn from a wellshuffled deck of 52 cards. The probability of drawing an ace is
A and B throw a pair of dice. If A throws 9, then B’s chance of throwing a higher number is
Total number of outcomes on throwing 2 dices = 6 × 6 = 36. Favourable outcomes are: {(4,6) (5,5), (6,4), (5,6), (6,5), (6,6)} Number of favourable outcomes = 6
∴ Probability of B throwing a number greater than 9 = (6/36) = 1/6
If the probability of an event is p, the probability of its complementary event will be:
Probability of selecting a bulb from a bag is 1/3 then probability of not selecting a bulb from bag is
A die is thrown once. The probability of getting a number 3 or 4 is
The probability of an event (other than sure and impossible event) lies between
A card is selected at random from a deck of 52 cards. The probability of its being a red face card is
A number is selected at random from first 20 numbers then probability that number is a multiple of 3 is :
