Why don't satellites in orbit fall to the ground? Why don't they fly off into space

2 answers:

They don't fall to the ground because their speed keeps them in orbit, ~18,000 mph

they don't wander off into space because they have navigation systems on board that keep them in the correct position in orbit.

When an experiment is conducted, one and only one of three mutually exclusive events S1, S2, and S3 can occur, with

Arturiano [62]

Answer:

$P(S_3|A) = \frac{2}{9}$

Explanation:

Given

$P(S1) = 0.3$ $P(S_2) = 0.5$ $P(S_3) = 0.2$

$P(A|S_1) = 0.3$ $P(A|S_2) = 0.1$ $P(A|S_3) = 0.2$

Required

Determine $P(S_3|A)$

Using Bayes' theorem:

$P(S_3|A) = \frac{P(S_3) * P(A|S_3)}{P(S_1) * P(A|S_1) + P(S_2) * P(A|S_2) + P(S_3) * P(A|S_3)}$

So, we have:

$P(S_3|A) = \frac{0.2 * 0.2}{0.3 * 0.3+ 0.5* 0.1 + 0.2 * 0.2}$

$P(S_3|A) = \frac{0.04}{0.18}$

Multiply by 100/100

$P(S_3|A) = \frac{4}{18}$

$P(S_3|A) = \frac{2}{9}$
