Question

In the unit, you found the probability of a compound event by identifying the sample space. However, it is also possible to find the probability of a compound event without finding the sample space. To do this, multiply the probability of the first event by the probability of the second event. For example, the probability of flipping heads twice on a coin is . Using this idea,1/2 x 1/2 =1/4 what is the probability that the next cougar and bear caught will both be unmarked?

Answer 2

13/25

Explanation:

Probability cougar will be unmarked :

⇒ Number of unmarked cougars / Total cougars

⇒ 865 - 173 / 865

⇒ 692/865

⇒ 4/5

============================================================

Probability bear will be unmarked :

⇒ Number of unmarked bears / Total bears

⇒ 1,940 - 679 / 1,940

⇒ 1,261/1,940

⇒ 13/20

===========================================================

Probability both will be unmarked :

⇒ 4/5 × 13/20

⇒ 52/100

⇒ 13/25
