An urn contains lottery tickets numbered from 1 to 100. If a ticket is...
Dude see....from 1 to 100...there is 10 perfect square number.
so, ur fav. number of out comes = 10.
nd number of total outcome = 100.
so....probability will be...no. of fav outcomes divided by number of total outcomes.
i.e., 10/100 => 1/10 => 0.1.
hope uh got it.
An urn contains lottery tickets numbered from 1 to 100. If a ticket is...
Introduction:
The problem states that an urn contains lottery tickets numbered from 1 to 100, and we need to find the probability that a randomly selected ticket is a perfect square.
Understanding the problem:
To solve this problem, we need to determine the total number of favorable outcomes (perfect square tickets) and the total number of possible outcomes (all tickets numbered from 1 to 100).
Finding the total number of favorable outcomes:
A perfect square is a number that can be expressed as the square of an integer. In the range from 1 to 100, there are 10 perfect squares: 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
Finding the total number of possible outcomes:
The total number of tickets in the urn is 100, so there are 100 possible outcomes.
Calculating the probability:
The probability of an event is calculated by dividing the number of favorable outcomes by the number of possible outcomes.
In this case, the number of favorable outcomes is 10 (the number of perfect squares from 1 to 100), and the number of possible outcomes is 100 (the total number of tickets).
Therefore, the probability of selecting a perfect square ticket is:
Probability = Number of favorable outcomes / Number of possible outcomes
= 10 / 100
= 0.1
Conclusion:
The probability that a randomly selected ticket from the urn is a perfect square is 0.1, which corresponds to option A.
