Abag contains 20 marbles of the same size that are blue, green, and red. the probability of picking a blue marble is 20%. the probability of picking a green marble is 50%. determine the probability of picking a red marble from the bag and then classify the probability of picking a red marble as likely or not likely to occur.

Hello!!

This is the correct answer.

Probability (Blue Marble) = 20%

Probability (Green Marble) = 50%

Probability (Red Marble) = ?

20% - 50% = 30%

The probability of picking a red marble from the bag is 30%.

Likely is defined as 50% so in this case, the probability of picking a red marble is not likely.

Hope this helps

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
