Answer» Answer: hey here is your answer pls mark it as brainliest Step-by-step explanation: so as we know that in a non-leap YEAR there are 365 days moreover 1 week=7 days THUS 365 days=365/7 weeks so thus 365 days has 52 weeks+1 odd day so this means there are 52 Saturdays+1 odd day so thus odd day can be any day out of 7 days in a week this now we have to calculate probability of these 7 days for getting 53 Saturdays so let the SAMPLE space be S thus S={Monday,Tuesdday,Wednesday, Thursday,Friday,Saturday} thus n(S)=7 now let A be the event of getting Saturday A={Saturday} so thus n(A)=1 now applying P(A)=n(A)/n(S) =1/7 thus P(A)=1/7 HENCE probability of getting 53 saturdays in a non-leap year is 1/7 |
