in 135 space shuttle missions, there were two failures. Based on these data, what's the probability of a successful mission?

98.518 repeating prercent

Step-by-step explanation:

2 out of 135 can also be written as 2/135

2 divided by 135 is 0.014814814814

that number is the percentage of failures

100% in decimal form is 1.00

1.00 subtracted by the percentage of failures is the percentage of successes

which is. 98518518518, 518 repeating move the decimal over 2 and you got the percentage 98.518 repeating
