a. I have five coins in my pocket – four are fair, and the other is weighted to have a 70% chance of coming up heads. I pull one

out at random and flip it three times. What is the conditional probability that I get four heads given I pulled out the weighted coin?

Answer:

The conditional probability that I get four heads given I pulled out the weighted coin = 0.2401

Step-by-step explanation:

Probability of getting 4 heads from 4 trials for a fair coin = 0.5⁴

But given that it is the weighted coin that is pulled out,

The probability of getting 4 heads from 4 trials = 0.7⁴ = 0 2401

HELP ME ASAP BRAINLIEST UP FOR GRABS
Volgvan

Answer:

52.0 m

Step-by-step explanation:

The triangle formed by the flagpole, the ground and the 30° line is a right triangle, with x as the required length to be found.

Using the tangent ratio

tan30° = \frac{opposite}{adjacent} = \frac{30}{x} ( multiply both sides by x )

x × tan30° = 30 ( divide both sides by tan30° )

x = \frac{30}{tan30} ≈ 52.0 m
