In a packet of 200 seeds 15 seeds will germinate. Find the probability that at least one of the 3 seeds taken from the packet will germinate.?

Sagot :

probability of seeds to germinate is = 15 seeds out of 200 seeds
                           Which is, 15/200 = 3/40 (Using 5 as LCM. 5 divides into 15 once & 5 into 200 forthy times) it cannot be simplified further so, wed say the probability of seeds to germinate is 3/40
