Answer: 3/8
Step-by-step explanation:
Since it is a fair coin, then generally, P(Head) = P(Tail) = ½
And since we've been asked to find the probability that the number of heads in the first two tosses be equal to the number of heads in the second two tosses, tossing a fair coin four times, the possible outcomes of having equal number of heads in first two tosses and second two tosses becomes:
[HHHH] or [HTHT] or [THTH] or [TTTT] or [HTTH] or [THHT]
=[½*½×½*½] + [½*½×½*½] + [½*½×½*½] + [½*½×½*½] + [½*½×½*½] + [½*½×½*½]
=1/16 * 6
=6/16
=3/8.
Answer:
Step-by-step explanation:
(2t+1)(t-4)
= 2t^2 - 8t + t - 4
= 27^2 - 7t - 4
Sorry, but I cannot understand the first part of this question
Nor the second part it's not finished.

This is never true. In a parallelogram, the diagonals will always bisect each other. Thus, each of these segments would always have to be equal.
