Ten identical cards are numbered 1 to 10. the cards are shuffled. one card is selected at random. what is the probability that the number written on it is: 10? 5? not 10? an odd number? a number less than 4? a number greater than 7?

To solve these, basically find out how many numbers satisfy your requirment, then divide that number by 10. Simplify your fraction and you have your probability.

probability of getting a 10: 1/10
probability of getting a 5: 1/10
probability of not getting 10: 9/10
probability of getting an odd number: 5/10
probability of getting a number less than 4: 3/10
probability of getting a number greater than 7: 3/10

Hope this helps, and muchas luck on your math!

A: 0.26 would be the answer

I’m vary good with science if you need with that
