Answer:
Step-by-step explanation:
if you can pick the same card 3 times the probability of winning is
but if you remove each card after you've picked them it's :
notice if you remove an odd card every time you pick one of them you are also removing one of the overall cards
and if you subtract these two you get :
which is like 4 percent
Answer:10
Step-by-step explanation:
12-5+3=10
All you have to do is substitute the numbers in the variables so it would be
14/1-7+4(5)
=14-7+4(5)
But you have to do pemdas so you would start with multiplication so it would be
=14-7+20
=7+20
=27
Multiply 30 and 12 and your answer will be 360
3. 20-(5x2). The answer is 10. [20-(5x2) -> 20-10=10]
4. B (Parenthesis are needed) and C (Start with simplifying the bottom).
5. 6x(9-3). The answer is 36. [6x(9-3) -> 6x6=36]
6. 10 divided by the difference of 6 and 4.
7. B
8. (5+7)x3 -> 12x3=36
