Answer:
57.6159 round if needed
Step-by-step explanation:
We know the length of the triangle which is 298. We know the base of the triangle which is 189.
We need to find angle of elevation so we must use tangent function.
Use inverse tan function
Round if needed.
The probability that the number of heads obtained from flipping the two fair coins is the same is 35/128.
Probability:
Probability means the fraction of favorable outcome and the total number of outcomes.
So it can be written as,
Probability = Favorable outcomes / Total outcomes
Given,
The coin a is flipped three times and coin b is flipped four times.
Here we need to find the probability that the number of heads obtained from flipping the two fair coins is the same.
We know that,
There are 4 ways that the same number of heads will be obtained;
0, 1, 2, or 3 heads.
The probability of both getting 0 heads is
Probability of getting 1 head,
Probability of getting 2 heads is,
And the probability of getting 3 heads is,
Therefore, the probability that the number of heads obtained from flipping the two fair coins is the same is,
=> (1/128) + (12/128) + (18/128) + (4/128)
=> 35/128.
