Find the probability that a student earns a
grade of B or C.
p = [?]
Enter a decimal rounded to the nearest hundrenth

0.71

Step-by-step explanation:

P( b or c) = P(b) + P(c) 0 P(b and c)

P(b) = 10/35 = 0.2857

P(c) = 15/35 = 0.42857142857

10/35 + 15/35 - 0 = 25/35, or 0.71

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

300pi
