Answer: 1</h3>
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.8 + 0.55 - 0.35
P(A or B) = 1.35 - 0.35
P(A or B) = 1
A probability of 1 means there is 100% certainty the event happens. This must mean that there are only possible outcomes are: either event A happens, or B happens, or possibly both A and B happen simultaneously.
Answer:
answer is 362,880
Step-by-step explanation:
9!= 9×8×7×6×5×4×3×2×1=362,880
O definitely does. I think Z and W do as well.
Y, K and P don't because they can't be rotated and map onto themselves.
Sandwiches are $5.25 Bowls are $3.50
4x+5y=38.50
3x+9y=47.25
Try this option:
1. the sides of the biggest triangle are 16; x and √(16²-x²); the sides of the smallest triange are x;5 and y. The smallest triangle ~ the biggest triangle. Using the property of the similar triangles:
2. according to the Pyphagorean theorem (in the smallest triangle):
answer: y=√55.
