Probability of independent event

Question

There is a stack of 10 cards he’s giving a different number from 1 to 10. Suppose we select a car randomly from the stat replace it and then randomly select another card. What is the probability that the first card is an odd number in a second card is less than three?

Answer 1

Hello Cece,

To find the probability of two steps, you usually multiply the probability for each step together.

In this case, you pick the first card and you want an odd number. What is the probability of picking an odd number from the numbers 1 to 10?

Then the second step, you have the same numbers from 1 to 10. What is the probability of picking a number less than 3?

Now multiply your two probabilities together to get the answer!

You may send in some work and a final answer for an expert to check.
