We know that:

When one card is drawn from a pack of 52 cards

The numbers of possible outcomes n(s) = 52

We know that there are 26 red cards in the pack of 52 cards
⇒ The numbers of favorable outcomes n(E) = 26

Probability of occurrence of an event: P(E)=Number of favorable outcomes/Numeber of possible outcomes=n(E)/n(S)

∴ required probability = 26/52 = 1/2.

Given that, upstream distance = 7 kms

Upstream speed = 7/42 x 60 = 10 kms

Speed of the stream = 3 kmph

Let speed in still water = M kmph, then

Upstream speed = M - 3 = 10

=> M = 13 kmph.

In the given series, 

 2nd term = 1st term + 12= 4 +1 = 5  

3rd term = 2nd term + 22 =5+4= 9  

4th term = 3rd term + 32 =9+9=18  

5th term = 4th term + 42 = 18+16=34 

Therefore, odd term is 32
