FIND THE INDICATED PROBABILITY FOR THE FOLLOWING:
luda_lava [24]

The value of the probability P(A) is 0.40

<h3>How to determine the probability?</h3>

The given parameters about the probability are

P(A or B) = 0.6

P(B) = 0.3

P(A and B) = 0.1

To calculate the probability P(A), we use the following formula

P(A and B) = P(A) + P(B) - P(A or B)

Substitute the known values in the above equation

0.1 = 0.3 + P(A) - 0.6

Collect the like terms

P(A)= 0.1 - 0.3 + 0.6

Evaluate the expression

P(A)= 0.4

Hence, the value of the probability P(A) is 0.40

Layla is saving up money for a trip. She already has $650 saved and plans to save an additional $150 each month for the trip. Co
jonny [76]

The amount of money that Layla has saved, s, is going to be what the equation equals. She earns $150 each month, so that would be 150m (slope intercept form equation s=em+b). B is the y-intercept, or the amount that Layla already has saved, which is positive $650.

Your equation is:

s=150m+650

I hope this helps :)
