Caroline, Krutika and Natasha share some sweets in the ratio 1:2:4. Caroline gets 14 sweets.
lisov135 [29]

Answer:

98 sweets

Step-by-step explanation:

Caroline got 14 sweets, ratio for her was 1.

Krutika had twice the bigger ratio than her, which means you have to multipy Carolines' sweets by 2. -> 14*2= 28

And do the same thing for Natasha which gives us the result of 56. 14*4= 56

And finally, you add all of those together and get 14+28+56=98.

Hope I helped! :)

Bin $A$ has one white ball and four black balls. Bin $B$ has three balls labeled $\$1$ and one ball labeled $\$7$. Bin $W$ has f
nydimaria [60]

Answer:

$20

Step-by-step explanation:

Bin A:                             Bin B:                  Bin W:

white ball: 20%              $1: 75%                $8: 5/6

black ball: 80%              $7: 25%               $500: 1/6

first we can calculate the expected return of bins B and W:

expected return if the ball is black = ($1 x 75%) + ($7 x 25%) = $2.50

expected return if the ball is white = ($8 x 5/6) + ($500 x 1/6) = $90

expected return of the game = (expected return of a black ball x probability of choosing a black ball) + (expected return of a white ball x probability of choosing a white ball) =($2.50 x 80%) + ($90 x 20%) = $2 + $18 = $20
