You flip a fair coin 7 times. What is the probability that the coin lands with the heads side up exactly 3 out of the 7 times?

Liono4ka [1.6K]

Answer:

35/128 ≈ 0.2374

Step-by-step explanation:

The number of combinations of 7 things taken 3 at a time is ...

7·6·5/(3·2·1) = 7·5 = 35

The number of sequences in which the coins can land is 2^7 = 128.

Of those 128 sequences, 35 will have exactly 3 heads.

The probability is 35/128.

What is the measure of segment PG?

agasfer [191]

The measure of the segment PG is mathematically given as

P G=17units. Option D

<h3>What is the measure of the segment PG?</h3>

Generally, the equation for is mathematically given as

$In $\triangle G H T$ \& $\triangle G J T$$

$\begin{aligned}&\angle G J T=\angle G H T \quad\left(\text { each } 90^{\circ}\right) \\\\&\angle G T J=\angle H T G\end{aligned}$

$G T=$ G $T$ (common)$

Hence $\triangle G H T=\triangle G J T$ (By AAS criteria)$

$G H=G J$ By cpct$

It is given that

$\mathrm{GH}=x+3$$$

$\ln =2 x-1$

Hence $G H=x+3=2 x-1$$$

$\text { as given } \begin{aligned}P G &=4 x+1 \\&=4 \times 4+1 \\&=17 \\\text { } & P G=17 \text { units }\end{aligned}$

In conclusion, The measure of the segment PG is given as

P G=17
