Answer:
Two
Step-by-step explanation:
The table is saying that, if Sandra swam enough races, she should expect to get 20 firsts, 12 seconds, 6 thirds, and two no placements.
Her expected value of points will be the average (mean) of all the points awarded for each race.
The average is the total number of points divided by the number of races.

The simulation says that, if she swam 40 races, she should expect to earn a total of 90 points.

She can't win a fraction of a point, so she can expect to win two points in her first race.

The mode is a term that is repeated the most.
And the one which is the repeated is 30.
I got:
37 times 3.79 = 140.23
You may need to verify.
