Answer:
÷ (could be x if you multiply by 1/6)
Step-by-step explanation:
It is literally the division symbol.
Answer:
12.56
Step-by-step explanation:
So, the circumference will be 4(3.14), which is 12.56. So, now you can solve for area. <em>By the way, the formula is: C = pi(d) (Just saying)</em>
Anyways, A = pi(r)2. So, with the radius being half of the diameter, you will cut 4 in half. You are now ready to solve.
A = 3.14 (2) (2), which is 12.56 .
Hope this helps! :)
Answer: 2.77
The expected value is positive, so you expect to gain on average $2.77 per draw.
================================================
Explanation:
Define two events
W = winning = getting a card 4 or less
L = losing = getting 5 or higher
P(W) = probability of winning
P(W) = 12/52 since there are 12 cards that are four or less out of 52
P(W) = 3/13 for any suit of 13, there are 3 cards that are four or less
P(L) = 1-P(W)
P(L) = 1-3/13
P(L) = 13/13 - 3/13
P(L) = 10/13
V(W) = net value of winning
V(W) = 162
V(L) = net value of losing
V(L) = -45
------------------
E(X) = expected value
E(X) = P(W)*V(W) + P(L)*V(L)
E(X) = (3/13)*162 + (10/13)*(-45)
E(X) = 36/13
E(X) = 2.76923076923077
E(X) = 2.77 rounding to two decimal places (to the nearest cent)
This game is in favor to the player since we got a positive expected value. A fair game would occur if the expected value was 0.
