Question

cards numbered 9 to 25 put in a box and mix well what is the probability of card to bear a perfect square number​

Answer 1

Answer:

perfect sq no in 9 to 25 is 9 , 16 , 25

no. of cards = 25 - 9 = 16

p(e) = n(e)/total

3/16

therefore 3/16 is the probability of getting a square no.

Answer 2

Concept:

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about how probable an event is to happen, or its chance of happening. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

Given:

Card numbered 9 to 25 putted in a box.

Find:

We have to find the probability of card to bear a perfect square number.

Solution:

First we have to find the total number of cards.

Total numbers of cards in a box = 25

Now we must determine the likelihood that the card chosen contains a perfect square number.

In this case, the perfect squares between 9 and 25 are: 9, 16, 25.

Number of perfect square cards = 3

Number of cards available = (25 - 9) = 16

So, Probability of card = Number of card/Total number of card

Probability of card = 3/16

Hence, the probability of card to bear a perfect square number​ is 3/16.
