Statistice Probability question!?

A random number generator is set to generate integer random numbers between 1 and 10 inclusive following a uniform distribution. What is the probability of the random number generator generating a 7 or lower?

How do I solve this?

    Within the range [1, 10] each number has a 1 in 10 chance of being generated- that's 1/10

    So there are 7 numbers between 1 and 7 inclusively and each of the numbers' probability of being generated is 1/10, and the question is what the probability of a 7 or lower being generated is. Thus you want to find out the probability of getting a 1 OR 2 OR 3... and so on, so you want to add the probabilities of each of these possibilities. 1/10 added 7 times (or 1/10 x 7) would be 7/10.

    Hope I helped!

    7/10= 70% probability
