A number is picked at random from the numbers 1to10. What is the probability that it is a perfect square
since when is 10 a perfect square?
P(square) = 3/10
You are correct that 10 is not a perfect square. Thank you for pointing that out.
The correct calculation for the probability of picking a perfect square from the numbers 1 to 10 is:
There are 3 perfect squares between 1 and 10: 1, 4, and 9.
The probability of picking a perfect square is therefore 3 out of 10:
P(perfect square) = 3/10 = 0.3
Therefore, the probability of picking a perfect square from the numbers 1 to 10 is 0.3 or 30%.
To find the probability of picking a perfect square number from 1 to 10, we need to determine the number of favorable outcomes (perfect squares) and the total number of possible outcomes.
Favorable outcomes:
The perfect square numbers from 1 to 10 are 1, 4, and 9.
Total outcomes:
The numbers from 1 to 10 are 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10.
Therefore, the probability of picking a perfect square number is:
P(perfect square) = (Number of favorable outcomes) / (Total number of outcomes)
P(perfect square) = 3 / 10
So, the probability of randomly picking a perfect square number from 1 to 10 is 3/10 or 0.3.
There are 4 perfect squares between 1 and 10: 1, 4, 9, and 10.
The probability of picking a perfect square is therefore 4 out of 10:
P(perfect square) = 4/10 = 2/5 = 0.4
Therefore, the probability of picking a perfect square from the numbers 1 to 10 is 0.4 or 40%.
