Answer:
0.25
Step-by-step explanation:
Givens
orange: 75
Blue: 62
Green: 52
Red: x
Total: 252
Equation
75 + 62 + 52 + x = 252 Collect the like terms on the left.
Solution
189 + x = 252 Subtract 189 from both sides
x = 252 - 189
x = 63 Red Ones
Probability
P(Red) = 63/252
P(Red) = 0.25

The ratio is 2 : 9
Step-by-step explanation:
Given:
The number of sports store = 4
The number of clothing store = 9
The number of jewellery stores = 5
To Find :
The ratio of number of sports stores to the total number of stores
Solution:
The ratio of number of sports stores to the total number of stores
= 
The total number of stores = number of sports store + number of clothing store + number of jewellery store
The total number of stores = 4 + 9 + 5
The total number of stores = 18
Now the ratio is
= 
or 4 : 8
The ratio after reduction is
=
or 2 : 9 or 2 to 9

Answer: option 1 is the correct answer
Step-by-step explanation:
Number of times for which the die was rolled is 360. It means that our sample size, n is 360.
The probability of rolling a 5 or a 6 is 1/3. It means that probability of success,p = 1/3. The probability of failure,q is
1 - probability of success. It becomes
1 - 1/3 = 2/3
The formula for standard deviation is expressed as
√npq. Therefore
Standard deviation = √360 × 1/3 × 2/3
= √80 = 8.9443
Standard deviation is approximately 8.9
