Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice. The product of Andrew's age and Chris'

stich3 [128]

Answer:

9

Step-by-step explanation:

A = B + 2

C = B - 3

A x C = 66

A = Andrew

C = Chris

B = Beatrice

Multiply A and c together

(B + 2) x (b - 3)

b^2 - 3b + 2b - 6

b^2 -b - 6 = 66

b^2 - b - 72 = 0

factors of -72b^2 that add up to - b are -9b + 8b

b^2 + 8b -9b - 72

b (b + 8) -9(b + 8)

b = 9 or - 8

b = 9

Lucia flips a coin three times. What is the probability she gets (Head, tail, Head) in that order?

Svetach [21]

Answer: $\dfrac{1}{8}$

Step-by-step explanation:

The total outcomes of tossing a coin = 2

The total number of possible outcomes of flipping coin three times =2 x 2 x 2 = 8

Favorable outcome= (Head, tail, Head) in order

i.e. Number of Favorable outcomes = 1

We know that , Probability = $\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

Therefore , The required probability $=\dfrac{1}{8}$

Hence , the probability she gets (Head, tail, Head) in that order $=\dfrac{1}{8}$
