Pizza Time has collected data about customer pizza topping preferences. They have calculated that P(pepperoni) = 0.7, P(olives)

Answer:

<u>Probability (Pepperoni and Olives) = 0.5</u>

Step-by-step explanation:

Given

Probability of pepperoni

Probability of olives

Probability of Pepperoni OR Olive

We need Probability of Pepperoni AND Olive

There is a probability formula for "AND" and "OR" probability. That is:

$P(A or B) = P(A) + P(B) - P(AandB)$

Let A be pepperoni and B be olives

So, we have:

P(A) = 0.7

P(B) = 0.6

P (A or B) = 0.8

Substituting in formula, we get our answer:

$P(A or B) = P(A) + P(B) - P(AandB)\\0.8=0.7+0.6-P(AandB)\\0.8=1.3-P(AandB)\\P(AandB)=0.5$

Hence,

<u>Probability (Pepperoni and Olives) = 0.5</u>

A bicyclist was going from point A to point B with a speed of 12 km/h. On the way back he increased his speed to 18 km/h and cov

zhenek [66]

The distance traveled by the certain object is the product of its speed and the time it traveled. Mathematically,

D = st
where s is the speed,and t is the time. Substituting the known values,

D = 12(x)

where x is the time in minutes.

D = 18(x - 15)

Equating the terms,

12(x) = 18(x - 15)

The value of x from the equation is 45 minutes or 0.75 hour.

D = (12 km/h)(0.75 h)
D = 9 km

Answer: 9 km
