<h3>
Answer: 0.93</h3>
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.2 + 0.8 - 0.07
P(A or B) = 0.93
Your answer would end up being 1.
6^2-7(8+6-3^2) = 1
7:9 because there are 35 children and 10 adults. Add 35 and 10 you get 35:45 then you simplify the ratio to get 7:9.

Answer:
Step-by-step explanation:
For the first symbol, there are 9 options to choose from. Then 8, then 7, and so on. Since each player chooses 5 symbols, they will have a total of 
permutations possible. Since the order of which they choose them matters (as a different order would be a completely different password), it's unnecessary to divide by the number of ways you can rearrange 5 distinct symbols. Therefore, the desired answer is 15,120.
