AGE |
NUMBER |
0 under 10 |
45 |
10 under 20 |
100 |
20 under 30 |
55 |
30 under 40 |
75 |
40 under 50 |
150 |
50 or more |
75 |
What is the probability that a person will be 50 or more? Please write in decimal form.
Solution -:
Total frequency = 500
The class 50 or more having frequency is 75
Therefore, we find
P(that a person age will be 50 or more)
The required probability is 0.15.
