Answer:
C
Step-by-step explanation:
This is a linear equation in one variable and has 1 solution
12x + 6 = 5x ( subtract 5x from both sides )
7x + 6 = 0 ( subtract 6 from both sides )
7x = - 6 ( divide both sides by 7 )
x = -
← 1 solution
In this question, the condition asked is two which was
1. The dice sum >7 (notice that >7 mean at least 8)
2. One of the two dice show a 2
It will be easier to fulfill the No.2 condition first so you can divide the probability into two,
Case 1: 1st dice show 2: then the second dice need to be 6 to made it sum>7
Case 2:2nd dice show 2: then the second dice need to be 6 to made it sum>7
The probability for a dice showing 2 is 1/6. The probability for a dice showing 6 is 1/6. Then the probability is 1/6 * 1/6= 1/36 for each case
Since case 1 and case 2 has same probability, then you just need to multiply 1/36 *2 = 1/18
345,000 ; 350,00 ; 300,000.
