Question

1. The probability that it will rain tomorrow is 0.25. What is the probability that it will not
rain tomorrow ?
2. If the mean of 7,8,x,11,14 is x, then x = ?
3. What is the probability that an ordinary year has 53 Sundays?​

Answer 1

Answer:

Find your answers below

Step-by-step explanation:

1. P ( Rain ) = 0.25

P( Not rain ) = 1 - 0.25

= 0.75

2. Mean = Sum of observation / Total no. of observation

X = 7 + 8 + x + 11 + 14 / 5

X = 40 + x / 5

5x = 40 + x

4x = 40

x = 10

3. Probability of getting 53 Sundays = 1/7
