Please help asap!!!!!!!!!!!!!!!
have fake nails on sorry about the last one

Answer 1

We start with 10 cards, 5 of which are red.

P(first card is red) = 5/10 = 1/2

Since this card is replaced, we still have the same 10 cards.

P(second card is red) = 5/10 = 1/2

P(both cards are red) = (1/2)(1/2)

= 1/4 = 25%
