15/16 is the probability that all 4 coins do not turn head upward at a time
Step-by-step explanation:
Probability of Head = 1/2
Probability of not head = 1 - 1/2 = 1/2
probability that all 4 coins do not turn head upward at a time
= 1 - Probability that 4 coins turn head upward at a time
= 1 - ⁴C₄(1/2)⁴(1/2)⁰
= 1 - 1/16
= 15/16
15/16 is the probability that all 4 coins do not turn head upward at a time
1600 * 15/16 = 1500
1500 times all 4 coins do not turn head upward at a time
