Answer: 4 %
Step-by-step explanation:
According to the question,
20% chance of heads landing face up
Therefore, probability of getting a head,
The probability of getting tail,
Thus, the probability that the coin will land with heads facing up both times
=
= 0.04 or 4 %
Thus the required probability is 4 %.
Answer:
If both number are over .50 then
Step-by-step explanation
Since 1 is 50 + 50, then we know
16.7
You need to use the pythagorean theorem
12, 60
To solve this question, we can use a system of equations
1) x + y = 76
2) y - 3x = 12
Then, we can use the second equation to isolate y and substitute it into the second equation
y = 3x + 12
x + (3x + 12) = 76
4x + 12 = 76
4x = 64
x = 16, y = 60
1
It is certain that the number rolled will be less than 14, so the probability is 1.
