Answer:

21 / 400

Step-by-step explanation:

Given 8 cherry, 5 grape, and 7 orange gummy vitamins out of the multivitamin container.

The probability that Julio will select an orange  multivitamin is

   7 ÷ 8 + 5 + 7 = 7/20

Also, given 11 berry, 3 lemon, and 6 pineapple  gummy vitamins out of the calcium container

The probability that Julio will select a lemon calcium is

3 ÷ 11 + 3 + 6 = 3/20

Therefore, since the event of selecting are independent of each other

probability that Julio will select an orange  multivitamin and a lemon calcium vitamin is

7/20 × 3/20

= 21 / 400

tbh i thought it was 21/40 uhm now im confused
