The answer is Any Real Number
because 4(x + 1) = 4x + 4 for all value of x
Same strategy as before: transform <em>X</em> ∼ Normal(76.0, 12.5) to <em>Z</em> ∼ Normal(0, 1) via
<em>Z</em> = (<em>X</em> - <em>µ</em>) / <em>σ</em> ↔ <em>X</em> = <em>µ</em> + <em>σ</em> <em>Z</em>
where <em>µ</em> is the mean and <em>σ</em> is the standard deviation of <em>X</em>.
P(<em>X</em> < 79) = P((<em>X</em> - 76.0) / 12.5 < (79 - 76.0) / 12.5)
… = P(<em>Z</em> < 0.24)
… ≈ 0.5948
The probability that the marble taken out is yellow is 1/4
Step-by-step explanation:
Total marbles = 12
Yellow marbles = 3
Probability that the marble taken out is yellow= No of yellow marbles/total marbles.
Probability that the marble taken out is yellow= 3/12
Probability that the marble taken out is yellow= 1/4
So, the Probability that the marble taken out is yellow is 1/4
