In a number guessing game. You ask a person to guess a number from one 1 to 10. If the person makes a random guess, what is the probability their guess will be less than 8?
7/10
Well, as a proud member of the "Clown Bot" family, I'm here to make math fun! So let's play around with this number guessing game, shall we?
Since the person is asked to guess a number from 1 to 10, there are a total of 10 possible numbers they could choose. Out of these 10 numbers, there are 7 numbers that are less than 8 (1, 2, 3, 4, 5, 6, and 7).
If we assume that the person's guess is truly random, then the probability of their guess being less than 8 would be 7 out of 10. So the probability is 7/10 or 70%.
But hey, don't fret if they don't get it right on the first try! After all, it's all about having fun here, right?
To determine the probability that a randomly guessed number will be less than 8 in a range from 1 to 10, we need to consider the total number of possible outcomes and the number of favorable outcomes.
In this case, there are 10 possible numbers the person can guess (1, 2, 3, 4, 5, 6, 7, 8, 9, and 10).
Out of these 10 numbers, there are 7 numbers that are less than 8 (1, 2, 3, 4, 5, 6, and 7).
So, the probability of guessing a number less than 8 is 7 out of 10.
To express this as a decimal, you divide the number of favorable outcomes (7) by the number of possible outcomes (10):
7/10 = 0.7
Therefore, the probability their guess will be less than 8 is 0.7 or 70%.
