I think it is 1/10 or 10% (This is also 0.1) of not winning the game
Answer: a) 0.2222, b) 0.3292, c) 0.1111
Step-by-step explanation:
Since we have given that
Let the probability of getting head be p.
Since, its head is twice as likely to occur as its tail.
a)If the coin is flipped 3 times, what is the probability of getting exactly 1 head?
So, here, n = 3
Now,
b)If the coin is flipped 5 times, what is the probability of getting exactly 2 tails?
2 tails means 3 heads.
So, it becomes,
c)If the coin is flipped 4 times, what is the probability of getting at least 3 tails?
Hence, a) 0.2222, b) 0.3292, c) 0.1111
therefore , <u>option</u><u> </u><u>(</u><u> </u><u>2</u><u> </u><u>)</u><u> </u><u>is </u><u>correct.</u>

Answer:
17/20
Step-by-step explanation:
+ -
common denominator is 20
15/20 + 16/20 - 14/20
17/20
Answer:
29
Step-by-step explanation:
Using PEMDAS, you will first evaluate the parenthesis, then exponents, (skip multiplication and division since it isn't in this problem), then addition/subtraction (order doesn't matter). So, plug in a and b where they correspond -> (3^3 - 8) which simplifies to (27 - 8) = 19. Finally add 10 + 19 = 29
hope this helps!
