Answer:
all 0.5
Step-by-step explanation:
Suppose this is a fair coin, so the chance of getting head vs tail is 50-50, or 0.5.
If you flip a coin, the chance of getting head is 0.5
If you flip a coin the 2nd time, this event is independent and unrelated to the previous result, hence the chance of getting head is still 0.5
If you flip a coin 25 times and all get head, then the chance of getting the next head is still 0.5. Because this event is still independent and not related to all the previous flips.
Good for mr brown. I wish I had a rail card
Given that (p - 1/p) = 4, the value of p² + 1/p² is 18. Detail below
<h3>Data obtained from the questio</h3>
- (p - 1/p) = 4
- p² + 1/p² = ?
<h3>How to determine the value of p² + 1/p²</h3>
(p - 1/p) = 4
Square both sides
(p - 1/p)² = (4)²
(p - 1/p)² = 16 ....(1)
Recall
(a - b)² = a² + b² - 2ab
Thus,
(p - 1/p)² = p² + 1/p² - (2 × p × 1/p)
(p - 1/p)² = p² + 1/p² - 2
From equation (1) above,
(p - 1/p)² = 16
Therefore,
p² + 1/p² - 2 = 16
Rearrange
p² + 1/p² = 16 + 2
p² + 1/p² = 18
Thus, the value of p² + 1/p² is 18
