Answer: 0.46
Step-by-step explanation: The first ting you need to do is find the total amount of candies in the bag in total. There are 139 candies. After that, find out the different probabilities for green and yellow separately. For green, you need to solve 45/139, and for yellow you need to solve 20/139. Once you find those values you add them together, resulting in your answer of 0.46 probability that picking one candy at random will result in either a green or yellow candy.
If we pick one candy at random, then the probability that it is green or yellow is 0.47(approx).
Probability is basically the measure of possibilities of an event to occur. It measures the number of possible outcomes from the total number of outcomes of an event.
No. of red candies = 42
No. of green candies = 45
No. of yellow candies = 20
No. of purple candies = 32
So, the total number of candies = (42+45+20+32) = 139
We know that, Probability = Favourable outcome/Total outcome
When the picked candy is green,
Favourable outcome = 45
∴ Probability = 45/139
Again, when the picked candy is yellow,
Favourable outcome = 20
∴ Probability = 20/139
Now, The probability of getting a green candy or a yellow candy= 45/139+20/139 = 65/139=0.47(approx)
