Answer:
Total number of cards in a standard deck of card=52
As deck of card contain 13 club +13 heart +13 spade+13 Diamond.
P(Diamond)=13/52 =1/4
If the card is not diamond then
P(not diamond)=39/52=3/4
Since after drawing card is not replaced
P ( second Diamond)=12/51
now if second card is not Diamond.then
P(non diamond)=39/51
Chances of your winning i.e both cards are diamonds=1/4×12/51=1/17=0.0588..(approx)
chances of your friend winning=1/4×39/51=[1/4]×[13/17]=13/68=0.1911..(approx)
Your friend has got better chance to win because there are more chances that both the cards are not Diamonds.

Answer:
-3
Step-by-step explanation:
(-3 * 5) / 5
(-15)/5
-15/5
=-3
1/3x+2 or x=1.5 depends on if u have to find x itself
16a. 5^3 could cancel 5^2 on denominator, same thing with 2^4 and 2^2. as a result, you should get 5*2^2/x^6 because when there is hidden 1 on x on the right side of the denominator
