Question

I need help solving please

Answer 1

It is given that there is deck of cards

There are 52 cards.

Among them there are 4 cards which are numbered 5.

Hence in first draw, the number posibilities is 4.

Hence the probability is

`(4)/(52)`

Similarly in the second draw the number of possibilites is 4 since the card is replaced.

Hence the probability is

`(4)/(52)`

Hence for five draws, the probability is

`(20)/(52)=(5)/(13)`
