Imagine that James has been bowling for over 10 years and never gets any better or any worse. The probability that he will bowl
vichka [17]

Answer:

5.01%

Step-by-step explanation:

In order to calculate a sequence of events you need to multiply the probability of each event happening with one another in decimal form. In this scenario, the probability of James bowling a strike is 55% meaning that the probability of James NOT bowling a strike is 45%. We want to know the probability of James NOT bowling a strike for 3 attempts and then bowling a strike on his fourth attempt. We first turn these probabilities into decimal form by dividing them by 100. And then multiply...

55 / 100 = 0.55

45 / 100 = 0.45

0.45 * 0.45 * 0.45 * 0.55 = 0.05011875

Multiply by 100 to get percentage.

0.05011875 * 100 = 5.01%

Add the difference between 180 and 130 to 70
laila [671]
For this question you can write an expression: (180-130)+70. First we need to find the difference between 180 and 130 which is 50. Now you can do 50+70 which equals 120.
