Dear student, Here is the solution of your asked query: so, probability that three numbers are consecutive=181140=3190Then, probability that they are not consecutive=1-3190=187190 Regards

Explain it

Explain it sol. (a) In a non-leap year' there are 365 days which have 52 weeks and 1 day. If this day is a Tuesday or Wednesday, then the year will have 53 Tuesday or 53 Wednesday. Required probability — 7 Q. 19 Three numbers are chosen from 1 to 20. Find the probability that they are not consecutive ....., 18, 186 (a) 190 187 190 188 190 18 (d) 20q (b) Since, the set of three consecutive numbers from 1 to 20 are 123, 234, 345, 19, 20 i.e., 18. 18 18 3 P (numbers are consecutive) = - 1140 190 3 187 P (three numbers are not consecutive) = 1 — — = 190 190 Q. 20 While shuffling a pack of 52 playing cards, 2 are accidentally dropped. Find the probability that the missing cards to be of different colours. , .26

Dear student,
Here is the solution of your asked query:

so, probability that three numbers are consecutive = \frac{18}{1140} = \frac{3}{190} Then, probability that they are not consecutive = 1 - \frac{3}{190} = \frac{187}{190}
