Answer 1

MARK ME AS THE BRAINLIEST

Answer:

1/10

Step-by-step explanation:

no. of perfect square b/n 1 to 80 = 8

therefore, probability = 8/80 = 1/10

Answer 2

Given:

Number of cards in the bag= 1 to 80

To find:

The probability that the card shows a perfect square​

Solution:

The probability that the card shows a perfect square​ is 1/10.

We can find the probability by taking the given steps-

We know that the probability of picking a card at random can be calculated by dividing the number of favorable outcomes by the total outcomes of picking the card.

The bag has cards from 1 to 80.

So, the total number of outcomes=80

Now, we know that between 1 and 80, the perfect squares of natural numbers are 1, 4, 9, 16, 25, 36, 49, 64.

The number of possible outcomes=8

The probability that the card shows a perfect square​=Total number of possible outcomes/ Total number of outcomes

On putting the values, we get

The probability that the card shows a perfect square​=8/80

=1/10

Therefore, the probability that the card shows a perfect square​ is 1/10.
