If a certain coin is flipped, the probability that the coin will land heads up is \small \frac{1}{2}. If the coin is flipped 5 t

Fittoniya [83]

Answer:

The probability of the heads up on the first three flips and not on the last two flips will be 1/32.

Step-by-step explanation:

As, the probability of head up when one time coin is flipped is 1/2. And it is said in the question that you must get heads in the first three flips.

So, for the first three flips the probability is = (1/2)^3 = 1/8

And for the last two flips you want to get not heads up.

Then, the probability is = (1/2)^2 = 1/4

Hence, your overall probability will be = 1/8 × 1/4 = 1/32 .

Help me find the solution set for 8x-3=2(x-1/2)

daser333 [38]

8x -3 = 2(x-1/2)
⇒ 8x -3= 2x -2*(1/2)
⇒ 8x -3 = 2x -1
⇒ 8x -2x= -1+ 3
⇒ 6x = 2
⇒ x= 2/6
⇒ x= 1/3

The final answer is x= 1/3~
