An oil company is drilling for oil at three sites. According to geological tests, the probabilities of

astra-53 [7]

Answer:

Step-by-step explanation:

Given

Probability of finding oil at site 1 is 0.30

Probability of finding oil at site 2 is 0.15

Probability of finding oil at site 3 is 0.20

Probability of Finding oil at all three sites

i.e. oil is present in all three sites simultaneously

$=0.3\times 0.15\times 0.20=0.009$

Probability of not finding oil at any of these sites $=(1-0.3)\cdot (1-0.15)\cdot (1-0.2)=0.476$

Complement of Finding oil at all three sites is equivalent to not finding the oil at all three sites

i.e. $A'\cap B'\cap C'$

Complement of not finding oil at any of the sites is equivalent to probability of finding oil at any of the given sites

$A\cup B' \cup C'$ or

$'\cup B \cup C'$ or

$A'\cup B' \cup C$

A roadside vegetable stand sells pumpkins for $5 each and squashes for $3 each. One day they sold 6 more squash than pumpkins, a

anygoal [31]

Rate at which each pumpkin is sold = $5
Rate at which each squash is sold = $3
Let us assume the number of pumpkins sold in a day = x
Then
The number of squash sold on that day = x + 6
Total amount of sales on that day = $98
Then
5x + 3( x + 6) = 98
5x + 3x + 18 = 98
8x = 98 - 18
8x = 80
x = 80/8
= 10
So
The number of pumpkins sold = 10
The number of squash sold = x + 6
= 10 + 6
= 16
