Convenience. She just asked whoever she saw.

Simple random sampling. There was no sort of grouping or anything involved, and they tell you random numbers were used.

121 of 162 said yes, so the experimental probability is 121/162
4055 * 121/162 = 3028.73... = 3029 people.

If I buy 3 4/5kg of cherries and 2 1/4 of strawberry's what is the Mass kilograms of fruit
lisov135 [29]
If you would like to know how many kilograms of fruit do you have, you can calculate this using the following steps:

3 4/5 kg of cherries + 2 1/4 kg of strawberries = 3 4/5 + 2 1/4 = 19/5 + 9/4 = 76/20 + 45/20 = (76 + 45) / 20 = 121/20 = 6 1/20 kg of fruit

The correct result would be 6 1/20 kilograms of fruit.
