Question

cards numbered 1 through 15 are mixed up and placed in a bag. Malik chooses one of the cards without looking. what is the probability that malik chooses a card with a number greater than or equal to 12? A. 4/5 B. 4/15 C. 1/4 D.1/5

Answer 1

Probability = (number of possible successes) / (total number of possibilities) .

The total number of possibilities on a single draw is 15.

How many cards are numbered greater than or equal to 12 ?

   12,  13,  14,  15

Four of them are.  So there are 4 possible ways for Malik to be successful.

Probability =  4 / 15 .
