Using it's concept, the probability that you flip heads and roll a number greater than 5 is:
.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, we have that:
- The probability of a head is 1/2.
- The probability of a number greater than 5 is 1/6.
Hence the probability of both events is:
.

Answer:
It goes over the goal post by 6 feet
Step-by-step explanation:
The football will be at the same x position as the goal when x = 40. When x = 40, y = -0.03 * 40² + 1.6 * 40 = 16. The height of the goal post can be represented by the equation y = 10. Since 16 > 10, the football goes over the goal post by 16 - 10 = 6 feet.
