A box contains cards numbered 6 to 50. A card is drawn at random from the box. The
probability that the drawn card has a number which is a perfect square like 4,9….is
(a) 1/45
(b) 2/15
(c) 4/45
(d) 1/9
Answers
Answer:
A perfect square is a number that can be expressed in form of a product of two integers that are equal.
Examples of perfect squares are :
1, 4 , 9 etc.
Between 6 and 50 the perfect squares in between are :
The list is as follows:
9, 16, 25, 36, 49
The probability that the drawn card has a number that is a perfect square will be given by :
Probability = Number of events/Total possible outcomes
Total possible outcomes ( 6 - 50) = 45
Number of perfect squares = 5
We express this as :
P(that the numbers are perfect squares) = 5/45
= 1/9
Step-by-step explanation:
Btw total number of outcomes=45
S=9,16,25,36,49
probability=5/45
=1/9
Solution
Total number of cards = 45
total possible outcomes = 45
the perfect square numbers between 6 and 50 are: 9, 16, 25, 36, 49
No. of cards bearing perfect square numbers = 5
no. of favorable outcomes = 5
required probability = no. of favorable outcomes/total possible outcomes
=
5
45
=
1
9
answer:- (d)
1
9
