Since there are 13 diamonds, there are 39 non diamonds (52-13)
To write a probability, you put the part over the whole
So you get 39/52 which is simplified to 3/4 so C
Hope this helps
A postulate isn't required to be proven
F(4) = 2(4)^3 -5
= 2(64) -5
= 128-5
= 123
Hope this helps!
Answer:
You can decide where to put the first digit because you know 153 doesn't fit into 6 or 61. But you know it can fit into 613. You put it there.
