What is the P(H,H,H,T,T) on 5 flips of a coin? I need help

meriva

Answer:

The probability for Heads will be 60% or 3/5.

The probability for Tails will be 40% or 2/5.

Step-by-step explanation:

The coin flipped 5 times and landed on Heads 3 times. This shows that out of 5 situations, 3 situations were Heads. Therefore, the probability is 3/5.

The coin landed on Tails 2/5 times the coin was flipped, which is basically the probability.

A, B, and C are collinear, and B is between A and C. The ratio of AB to BC is 1:4.

schepotkina [342]

Let point C has coordinates $(x_C,y_C).$ Consider vectors

$\overrightarrow{AB}=(x_B-x_A,y_B-y_A)=(8-9,6-9)=(-1,-3),\\ \\\overrightarrow{BC}=(x_C-x_B,y_C-y_B)=(x_C-8,y_C-6).$

Since the ratio AB to BC is 1:4, you have that

$\dfrac{-1}{x_C-8}=\dfrac{1}{4}\quad \text{and}\quad \dfrac{-3}{y_C-6}=\dfrac{1}{4}.$

Find $x_C$ and $y_C:$

$x_C-8=-4,\\ \\x_C=-4+8=4,\\ \\y_C-6=-3\cdot 4=-12,\\ \\y_C=-12+6=-6.$

Yuri [45]

Answer:

first method

22=5

7. x

we cross multiply to get

22x= 5×7

22. 22.

x= 35

=1.59

second method

22=5

7. x

we multiply the denominators to get 7x

then we multiply each term by 7x

7x×22 = 5×7x

7. x

here the 7 and 7 will cancel out and the x and x will cancel out to get

22x= 35

22. 22

= 1.59
