Answer:
72:48
Step-by-step explanation:
as you divide 120 by 5 as 3+2=5 and that equals 24
24x3=72
24x2=48

Answer:
The total number of games won by Unicorn is 40.
Step-by-step explanation:
- We are given with a word problem
- We are asked to find the number of unicorns played during the season
- We can do this in two steps
Step 1: Finding the win percentage
Step 2: Finding the number of unicorns played during the season
Step 1 of 2
Let the number of games played by unicorn be x.The unicorn won 60% of the first x-10 games That is 
Combining the 8 games we get,

Step 2 of 2
The unicorn totally won 65% of the games played.
That is 
Equating both the equation gives

Answer:
So, we can do it in 720 ways.
Step-by-step explanation:
We have been given total of six trophies to arrange in the top shelf of the bookcase
If we need to arrange n things in different ways we can do it in n! ways
Similarly, Here we will do it in 6! ways
n!=n(n-1)(n-2).....1
So, 6!=6 x 5 x 4 x 3 x 2 x 1=720
This is a binomial distribution with n = 5, p = 0.55, q = 1 - 0.55 = 0.45, x = 0, 1, 2, 3
P(x) = nCx p^x q^(n - x)
P(x ≤ 3) = 1 - P(x > 3) = 1 - [P(4) + P(5)]
P(4) = 5C4 x (0.55)^4 x (0.45) = 0.2059
P(5) = 5C5 x (0.55)^5 x 1 = 0.0503
P(x ≤ 3) = 1 - (0.2059 + 0.0503) = 1 - 0.2562 = 0.7438
