Answer:
The width of the school campus is:
Step-by-step explanation:
Scale = 1.5 inches : 10 feet
That means, 1.5 inches is equals to 10 feet in real.
Then for 1 inch:
⇛ 10 / 1.5 feet
⇛ 10/3 feet
We need to find for 94.5 inches,
⇛ 94.5 inches = 94.5 × 2/3 feet
⇛ 94.5 inches = 63 feet
Thus, the width of the school campus is <u>6</u><u>3</u><u> </u><u>feet</u>.
The probability of winning 15 out of the 22 games is
We know that the probability of winning on the arcade game is 0.568.
Then the probability of losing is:
P = 1 - 0.568 = 0.432
The probability of winning 15 out of 22 games is given by the equation:
Where C(22, 15) is the number of combinations of 15 elements that we can make with a set of 22 elements, given by:
Then the probability is:
