60.4% probability that a randomly selected U. S. adult weighs more than the healthy weight range

Step-by-step explanation:

We have these following probabilities:

1.9% probability that a randomly selected U. S. adult is underweight.

37.7% probability that a randomly selected U. S. adult has healthy weight.

35% probability that a randomly selected U. S. adult is overweight.

25.4% probability that a randomly selected U. S. adult is obese.

Based on this data, what is the probability that a randomly selected U. S. adult weighs more than the healthy weight range?

More than the healthy weight range: overweight or obese

35% + 25.4% = 60.4%

60.4% probability that a randomly selected U. S. adult weighs more than the healthy weight range
