Suppose we toss a weighted coin, for which the probability of getting a head (H) is 60% . i) If we toss this coin 3 times, then the probability of getting exactly two heads (to two decimal places) is 54/125 ii) If we toss this coin 5 times, then the probability of getting exactly four heads (to two decimal places) is 0.2592 iii) if we toss this coin 10 times, then the probability of getting 8 or more heads (to two decimal places) is 123201/39 n Note: you can use Maple to evaluate the binomial coefficient using the command k binomial (n , k) . A similar feature should exist on your handheld calculators
