A market trader has 100 oranges for sale 4 of them are unripe what is the probability that an orange chosen at random is ripe
To find the probability that an orange chosen at random is ripe, we need to know how many ripe oranges are there.
If the trader has a total of 100 oranges and 4 of them are unripe, then the number of ripe oranges can be calculated by subtracting the number of unripe oranges from the total number of oranges:
Number of ripe oranges = Total number of oranges - Number of unripe oranges
= 100 - 4
= 96
Now, the probability that an orange chosen at random is ripe can be calculated by dividing the number of ripe oranges by the total number of oranges:
Probability of choosing a ripe orange = Number of ripe oranges / Total number of oranges
= 96 / 100
= 0.96
Therefore, the probability that an orange chosen at random is ripe is 0.96 or 96%.
