Please help me with this probability problem.

0.308

Step-by-step explanation:

You have 8 nickels and 6 dimes. 8 + 6 = 14.

You know both of the coins you have picked are nickels so you will have to find the probability of picking a nickel and then another nickel.

First time: is the probability of picking a nickel the first time.

Second time: Since you don't have a nickel in your pocket anymore, you now have 7 nickels and 6 six dimes in your pocket. Together you have 13 coins. You have 7 nickels so you have a chance of picking another nickel out of your pocket.

To find the probability of this event you do * because to find the probability of A and B you do P(A) multiplied by P(B). If you wanted to find the probability of getting A or B you would add together instead of multiplying.

Multiplying these together gets you 0.307692... which is 0.308 rounded.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
