If there are 6 tadpoles in a tank and 2 angel fishes, the probability of selecting one tadpole or one angel fish would be?
The probability of selecting one tadpole or one angel fish would be 3/4 (3 out of 4 total fish).
Well, I hope you're not planning to have a tea party with those tadpoles and angel fishes because the probability of selecting either a tadpole or an angel fish would depend on the total number of options you have. So, if you have a total of 8 organisms in the tank (6 tadpoles + 2 angel fishes), the probability of selecting either one would be (6 + 2) / 8, which simplifies to 8/8, or 1. So, you've got a 100% chance of choosing either a tadpole or an angel fish. Just remember to bring some party hats for the tadpoles, they might feel left out without them!
To find the probability of selecting one tadpole or one angel fish, we need to consider the total number of possible outcomes and the number of favorable outcomes.
Step 1: Determine the total number of possible outcomes.
In this case, we have 6 tadpoles and 2 angel fishes. Therefore, the total number of possible outcomes is 6 + 2 = 8.
Step 2: Determine the number of favorable outcomes.
Since we want to select one tadpole or one angel fish, we count the number of tadpoles and angel fishes separately.
Number of favorable outcomes for tadpoles: 6
Number of favorable outcomes for angel fishes: 2
Step 3: Determine the probability.
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability of selecting one tadpole or one angel fish = (Number of favorable outcomes for tadpoles + Number of favorable outcomes for angel fishes) / Total number of possible outcomes
= (6 + 2) / 8
= 8 / 8
= 1
Therefore, the probability of selecting one tadpole or one angel fish would be 1, or 100%.
To calculate the probability of selecting one tadpole or one angel fish, we need to know the total number of options and the number of favorable outcomes.
The total number of options is the sum of the tadpoles and angel fishes, which is 6 tadpoles + 2 angel fishes = 8.
The number of favorable outcomes is the number of tadpoles (6) plus the number of angel fishes (2) since we want to select either a tadpole or an angel fish.
So, the probability of selecting one tadpole or one angel fish would be:
Number of favorable outcomes / Total number of options
= (Number of tadpoles + Number of angel fishes) / (Number of tadpoles + Number of angel fishes)
= (6 + 2) / 8
= 8 / 8
= 1
Therefore, the probability is equal to 1 or 100%. This means there is a 100% chance of selecting either a tadpole or an angel fish from the tank.
