Probability

Please indicate whether below statements are True or False? (explain shortly why):

1. If events A and B are independent, then P(A/B) is always equal to zero.

2. If events A and B are mutually exclusive, then P(A/B) is always equal to zero.

3. If the probability of success is 0.4 and the number of trials in a binomial distribution is 150, then its standard deviation is 36.

4. If a fair coin is tossed 100 times, then the variance of the random variable defined as the number of heads is exactly five.

5. If a fair coin is tossed 20 times then the probability of exactly 10 Tails is more than 15 percent.
