An oil-drilling company knows that it costs $25,000 to sink a test well. if oil is hit, the income for the drilling company will be $825,000. if only natural gas is hit, the income will be $225,000. if nothing is hit, there will be no income. if the probability of hitting oil is 1/40 and if the probability of hitting gas is 1/20, what is the expectation for the drilling company? $

The expectation for the drilling company is $6,875.

Step-by-step explanation:

is the income that is expected in relation to natural gas being hit. There is a 1/20 probability that gas is hit. If gas is hit, the income will be $225,000. So

is the income that is expected in relation to oil being hit. There is a 1/40 probability that oil is hit. If oil is hit, the income will be $825,000. So

25,000 is subtracted from the expectation because it is the cost to sink a test well.

The expectation is:

The expectation for the drilling company is $6,875.

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

=

10
