A teacher made a pack of 50 cards and
numbered them 1 to 50. She asked one of the students to pick a card . what is the probability that the card picked is : (i) a multiple of 5?
Answers
Answer:
sample space =50
n(s)=50
Let 'A: be the Event : a multiple of 5
A={5,10,15,20,25,30,35,40,45,50}
n(A)=10
P(A)=n(a)
n(s)
P(A)=10
50
P(A)=1
5
Step-by-step explanation:
Given:-
A teacher made a pack of 50 cards and
numbered them 1 to 50. She asked one of the students to pick a card .
To find:-
what is the probability that the card picked is : (i) a multiple of 5?
Solution:-
Numbers on the cards =from 1 to 50
Sample space={1,2,3...,50}
Total number of numbers =50
Total number of possible outcomes=50
Multiples of 5=5,10,15,20,25,30,35,40,45,50
Number of favourable outcomes=10
Picking up a card from the given pack of 50 cards is a random experiment and multiple of 5 is an event then
Probability of an Event=P(E)=
No. of Favourable outcomes/Total no. of possible outcomes
Probability of getting a multiple of 5=
P(5)=10/50
P(5)=1/5
Answer:-
Probability of getting a multiple of 5=1/5
Used Formula:-
Probability of an event=P(E)=
Number of favourable outcomes/Total number of possible outcomes
