Two friends A and B visited a shop on any one of the day of every week.A visited from Monday to Friday and B visited from Wednesday to Saturday. Then find the probability of the following:
a) same day
b) consecutive days
c) different days
Answers
Answer:
Total no. Of days A visited-5
Total no. Of days B visited- 4
Total outcomes- 7
Step-by-step explanation:
1. Same days
Favourable outcomes- 3
Total no. Of outcome-7
Probability=favourable outcomes/total outcome
= 3/7
2. Consecutive days
Probability= favourable outcomes/total outcomes
= 7/7
= 1
3. Different days
Favourable outcomes- 3
Total outcomes- 7
Probability= favourable outcomes/ Total outcomes
= 3/7
Step-by-step explanation:
ACCORDING TO THE QUESTION
GIVEN:-
A(FRIEND) DAYS OF VISITING IS :- MONDAY TO FRIDAY
B(FRIEND) DAYS OF VISITING IS :- WEDNESDAY TO SATURDAY
A) PROBABILITY ( E ) =FAVOURABLE OUTCOMES /TOTAL NO. OF OUTCOMES
SAME DAY = WEDNESDAY, THURSDAY, FRIDAY
=3
P ( E ) = 3 / 7
TOTAL NO. IS 7
7 DAYS = WEEKS
B ) P ( Two friends A and B visited the shop on CONSECUTIVE day ) = 3 / 7
C ) DIFFERENT DAYS
FOR A = MONDAY , TUESDAY
FOR B = SATURDAY
P( E ) = 3/7
