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%

Answer:
The number is 63.
Step-by-sep explanation:
Let the 2 digits be x and y where the number is xy.
x + y = 9............................(1)
Also if we subtract 27:
10x+y - 27 = 10y + x
9x - 9y = 27 Divide this through by 9:
x - y = 3 ............................(2)
Adding equations (1) and (2):
2x = 12
x = 6.
Substituting in (1):
6 + y = 9
y = 3.
