Answer:
0.69 miles per hour
Step-by-step explanation:
speed = distance/time
speed = 506/723
506/723 = 0.69
Response:
P(largest or smallest) = 0.30 + 0.20 - 0.15
Detailed explanation
You add the probabilities of choosing the largest and smallest without double counting the chance of selecting both.
<span>As the restaurant owner,
The likelihood of hiring Jun is 0.7 => p(J)
The likelihood of hiring Deron stands at 0.4 => p(D)
The chance of hiring at least one of them is 0.9 => p(J or D)
We can formulate the probability equation:
p(J or D) = p(J) + p(D) - p(J and D) => 0.9 = 0.7 + 0.4 - p(J and D)
p(J and D) = 1.1 - 0.9 = 0.2
Thus, the probability that both Jun and Deron are hired is 0.2.</span>
