Answer:
Step-by-step explanation:
The triangles are drawn below.
CD is perpendicular to AB as CD is height to AB.
Therefore, angles °
So, triangles ΔCBD and ΔCAD are right angled triangles.
Now, from the right angled triangle ΔABC,
From ΔCBD,
is same as .
So,
Now, from ΔCAD,
is same as
So,
Hence, the unknown angles of both the triangles are:
Answer:
<u><em>a) P(X=1) = 0.302526</em></u>
<u><em>b) P(X=5) = 0.010206</em></u>
<u><em>c) P(X=3) = 0.18522</em></u>
<u><em>d) P(X≤3) = 0.92953</em></u>
<u><em>e) P(X≥5) = 0.010935</em></u>
<u><em>f) P(X≤4) = 0.989065</em></u>
