Difference between two number means the subtraction between them.
Therefore, "<span>The difference between a number and 12 is 20" means that when subtracting these two numbers, the result is 20.

Since the question did not mention which number is greater, therefore, we have two ways to write the equation.
These two ways are as follows:
x - 12 = 20, and
12 - x = 20

Step-by-step explanation:

Band Sports Debate Total

Male 105 320 7 432

Female 105 160 14 279

Total 210 480 21 711

P(female or plays sports)

We want the probability that they are female or play sports, but we cannot double count the female sports players, so we subtract them

P(female) + P (sports) - (female and sports)

female/total + sports/total - female sports/ total

279/711 + 480/711 - 160/711

599/711
