Question

1)Гроші вкладаються в два бізнес – проекти. Перший бізнес – проект може бути успішним з імовірністю p1 , а другий з імовірністю p2  незалежно від успішності першого. З якою імовірністю обидва бізнес – проекти будуть успішними? (1-p1)(1-p2);(1-p1)p2;p1p2;p1(1-p2).2)Підкидають 3 монети. Яка імовірність того, що на всіх монетах випадуть решки?​

Answer 1

Ответ:

p1p2

імовірність того, що на всіх трьох монетах випадуть "решки", дорівнює 1/8 або 0.125.

Answer 2

Probability of both business projects being successful

To determine the probability of both business projects being successful, we need to consider the individual probabilities of success for each project. Let's assume the first project has a probability of success of p1, and the second project has a probability of success of p2.

The probability of both projects being successful can be calculated by multiplying the probabilities of success for each project. Therefore, the probability of both projects being successful is given by:

p1 * p2

This formula assumes that the success of one project does not affect the success of the other project.

Probability of getting all heads when flipping three coins

When flipping three coins, each coin has two possible outcomes: heads or tails. Since we want to calculate the probability of getting all heads, we need to determine the probability of getting heads on each individual coin flip.

The probability of getting heads on a single coin flip is 1/2, as there are two equally likely outcomes (heads or tails).

To find the probability of getting all heads on three coin flips, we need to multiply the probabilities of getting heads on each individual flip. Since each flip is independent, the probability of getting all heads is:

(1/2) * (1/2) * (1/2) = 1/8

Therefore, the probability of getting all heads when flipping three coins is 1/8.
