A bag contains card numbered 1 to 49 a card is drawn from the bag at random after mixing the cards find the probability that the number drawn on the card is
1st a perfect square
2nd and even prime numbers
Answers
Answer:
Step-by-step explanation: (i) From 1 to 49 there are following perfect sqaures - 1, 4, 9, 16, 25, 36 and 49.
Probability = no. Of favorable outcomes\Total no. Of outcomes
=7\49 = 1\7
(ii) find prime no. Between 1 and 49
2.3.5.7.11.13.17.19.23.29.31.37.41.43.47
Find even among them
2.
So probability = 1\49
Answer:
1st:
1,4,9,16,25,36,49, are the numbers that are perfect square of 1,2,3,4,5,6,7, respectively and are between 1 to 49.
So: the probability be
favourable case = (1,4,9,16,25,36,49) = 7
total case = 49
P(E) = favourable case/ total case
7/49
= 1/7 Ans.
2nd:
Even prime number between 1 and 49
The prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47 .
: Probability of even number.
favourable case = 2 is only even prime number between 1 and 49 , so the favourable case is 1
P(E) = fAVOURABLE CASE / TOTAL CASE
1/49 Ans.
