Answer: A = 9

B = 11

C = 4

Step-by-step explanation:

A + B = 20

A + C = 13

B + C = 15

A + B + C = 24

Substitute 20 into our final equation for A + B.

20 + C = 24. Subtract 20 from each side.

C = 4.

Remember, B + C = 15. Substitute 4 into C to solve for B.

B + 4 = 15. Subtract 4 from both sides.

B = 11

Remember, A + B = 20. Substitute 11 for B to solve for A.

A + 11 = 20. Subtract 11 from both sides.

A = 9.

andriy [413]

Answer:

(19/99) = 0.192

Step-by-step explanation:

Numbers 1 to 99, that is 99 numbers (obtained through the equation for the nth term of an AP)

L = a + (n-1) d

L = nth term = 99

a = first term = 1

n = number of terms = ?

d = common difference = 1

99 = 1 + (n-1)1

n = 99

Sample space = 99

The numbers that include at least, a 1 are

1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 31, 41, 51, 61, 71, 81, 91

19 numbers.

Probability of randomly selecting a card where the number contains at least one digit 1 from 1 to 99 = (19/99) = 0.192

Hope this Helps!!!
