If 40% of the pizzas arrive on time, then 60% of the pizzas will be late.
Change the percent to a decimal: 60% = 0.6
Four late pizzas in a row = 0.6^4 = 0.1296
a) The probability that the first four deliveries will be late is 12.96%.
b) 40% of the pizzas arrive on time. 40% is equal to 2/5. Therefore, it is expected the first and second pizzas will be late, and the third pizza will be on time.
