Cards, marked with numbers 5 to 50, are placed in a box and mixed thoughly. A card is drown from the box at random. Find the probability that the number on the taken out card is:
1) a poime number less than 10
2)A number which is a perfect squar.
Answers
Answer:
a)2/45
b) 1/9
Step-by-step explanation:
this is the answer
Step-by-step explanation:
a)probability=1/23
b) probability=5/46
Given=Cards, marked with numbers 5 to 50, are placed in a box and mixed thoughly. A card is drown from the box at random.
To Find=the probability that the number on the taken out card is:
1) a prime number less than 10
2)A number which is a perfect squar.
Probability=Favourable outcome/Total no. of outcome
cards marked with no. 5-50
The sample size is 46
a) a prime number less than 10
Favourable outcome ( a prime no.less than 10)=5 and 7=2
total no. of outcome=46
probability of a prime number less than 10
=2/46
=1/23
b)A number which is a perfect square.
Favourable outcome (a no. which is a perfect square)=9,16,25,36,49=45
Total no. of outcome=46
probability of a no. which is a perfect square
probability=5/46
