4. An observer at the top of a 40-foot cliff spots two boats sailing in a straight line with her. The
Tems11 [23]

Answer:

The two bolts of 50.9 ft apart

Step-by-step explanation:

boat 1

\tan(21)  =  \frac{45.33}{x}  \\ x =  \frac{45.33}{ \tan(21) }  \\ x = 118.1 \: ft

boat 2

\tan(34)  =  \frac{45.33}{x}  \\ x =  \frac{45.33}{ \tan(34) }  \\ x = 67.2 \: ft

118.1 - 67.2 = 50.9 \: ft

Which rule states that when two outcomes are independent, the probability that these outcomes occur together is the product of t
charle [14.2K]

The rule which states that when two outcomes are independent, the probability that these outcomes occur together is the product of their individual probabilities is "Multiplicative rule".

<h3>What is Multiplicative rule?</h3>

The likelihood of both events A and B occurring, in accordance with the probability multiplication rule, is equal to the product of the probability of B occurring and the conditional probability of event A occurring given that event B occurs.

If A and B are dependent events, then the probability of both events occurring simultaneously is given by:

P(A \cap B)=P(B) \cdot P(A \mid B)

The likelihood of both events occurring simultaneously in an experiment where A and B are two independent events is given by:

P(A \cap B)=P(A) \cdot P(B)

Multiplication Theorem of Probability:

The multiplication guidelines that we use in probability have already been taught to us, including;

\begin{aligned}&P(A \cap B)=P(A) \times P(B \mid A) \text {; if } P(A) \neq 0 \\&P(A \cap B)=P(B) \times P(A \mid B) \text {; if } P(B) \neq 0\end{aligned}

Therefore, the relationship between two events is explained by the probability multiplication rule.

Set AB represents the events in which both events A and B have occurred for two events A and B related to a sample space S.

Consequently, (AB) indicates that occurrences A and B happened at the same time. You can write the event AB as AB.

Using the characteristics of conditional probability, the likelihood of event AB is calculated.
