3. A lot of 24 bulbs contain 25% defective bulbs. A bulb is drawn at random from the lot. It is found to be not defective and it is not put back. Now, one bulb is drawn at random from the rest. What is the probability that this bulb is not defective? ( 4. When 3 coins are tossed randomly 250 times and it is found that three heads appeared 70 times, two heads appeared 55 times, one head appeared 75 times and no head appeared 50 times. a. If three coins are tossed simultaneously at random, find the probability of getting three heads? b. If three coins are tossed simultaneously at random, find the probability of getting two heads? 5. Let's suppose there are thirteen balls in a box. Five balls are Green(G), and eight balls are Red(R). If we draw two balls, one at a time, with replacement, find the probability of the following events: a. Both Balls are Green b. Both balls are Red c. The first ball is Green and the second is Red d. The first ball is Red and the second is Green.
