Question
- A bag has 3 red balls and 5 green balls. If we take a ball from the bag, then what is the probability of getting red balls only?(a) 3(b) 8(c) ⅜(d) 8/3
Solution
The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes.
In this case, the favorable outcome is drawing a red ball, and there are 3 red balls. The total number of outcomes is the total number of balls, which is 3 (red) + 5 (green) = 8.
So, the probability (P) of drawing a red ball is:
P(Red) = Number of red balls / Total number of balls = 3 / 8
So, the correct answer is (c) ⅜.
