A box contains 10 cards on which one of
the numbers 1, 2, 3, 4.......10 is written in each
Card. One card is taken from the box at random.
a) what is the probability of getting an even numbered card?
(b) what is the probability and getting an odd numbered card?
(c) what is the probability of getting a card on which a prime number is written?
(d)what is the probability of getting a perfect square on the card?
Answers
Answer:
Step-by-step explanation:
Total number of outcomes=10
a) No of even number= 2,4,6,8,10= 5
therefore, P( getting an even numbered card) = 5/10=1/2
b) No of odd numbers= 1,3,5,7,9 =5
therefore, P(getting an odd numbered card)= 5/10= 1/2
c) No of prime numbers=2,3,5,7= 4
probability= 4/10=2/5
d)perfect square= 4,9= 2
Probability= 2/10=1/5
hope it helped you !
Answer: The answers are
a)1/2
b)1/2
c)2/5
d)3/10
Step-by-step explanation:
Probability of occurrence of an Event = Number of favourable outcomes/Total number of outcomes.
So, the answers are;
a) The probability of getting an even number is asked.
Number of even numbers between 1-10 are 2,4,6,8,10 that is there are 5 even numbers.
So as per the above sentence (1);
Probability = Number of favourable outcomes/Total number of outcomes.
Probability = 5/105/10 in standard form is 1/2.
SO, answer is 1/2.
b) The probability of getting an odd number is asked.
Number of odd numbers between 1-10 are 1,3,5,7,9 that is there are 5 odd numbers.
Probability = Number of favourable outcomes/Total number of outcomes.
Probability = 5/10
5/10 in standard form is 1/2.
SO, answer is 1/2.
c) The probability of getting a card on which a prime number is written is asked.
Number of prime numbers between 1-10 are 2,3,5,7 that is there are 4 prime numbers.
Probability = Number of favourable outcomes/Total number of outcomes.
Probability = 4/10
4/10 in standard form is 2/5.
So, answer is 2/5.
d) The Probability of getting a perfect square on the card is asked.
Number of perfect squares between 1-10 are 1,4,9 that is there are 3 perfect squares.
Probability = Number of favourable outcomes/Total number of outcomes.
Probability = 3/10
3/10 can't be written in standard form.
So, answer is 3/10.
This is my first answer....... please don't mind if any mistake is spotted☺️☺️
