their are two boxes each one contains paper slips marked 1to 10 if we take one from each what is the probability of both being prime |
|
Answer» if we DRAW one slip from each box, total NUMBER of possible PAIRS=10×10=100Prime numbers between 1 and 10 are 2,3,5 and 7.Thus, there are 4 PRIME numbers in each box.⇒ Number of pairs such that two slips are prime =4×4=16Thus, probability that both the slips are prime =10016=254 |
