Answer:
0.3
Step-by-step explanation:
1.00, or 100%. is the total of all probabilities
In the Venn diagram, we have the probabilities 0.2, 0.4 and 0.1;their sum will be 0.2+0.4+0.1 = 0.6+0.1 = 0.7.
We are left with 1.00-0.7 = 0.3 i.e the remaining probability of no toppings.
As the mean is 90 then, the sum of the quantities are..
90×4 = 360
the scores you have are 86, 85, 96
so the answer is.
85+86+96= 262
360-262= 98
the fourth score is 98.
