Probability equation need help again. worded problem-the table below displays the number of siblings for students. at one school. Find the probability that a randomly selected students has 2 siblings. There's probably another step? Because My answer doesn't match my worksheet. A) 0,215 B) 0.202 C)0.283 D)0.125

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
