Question

The type of fish caught in the Charleston Harbor in March was recorded for a month. The results are recorded in the table below. What is the probability that the next fish caught is a drum or sea trout? Enter a fraction or round your answer to four decimal places if necessary

Answer 1

Step-by-step explanation:

Probability is expressed as

number of favorable outcomes/number of total outcomes

From the information given,

Total number of fishes = 251 + 374 + 198 + 261 + 225 = 1309

number of drums = 374 + 198 = 572

Probability of getting a drum = 572/1309

number of sea trout = 225

Probability of getting a sea trout = 225/1309

Since the events are independent,

the probability that the next fish caught is a drum or sea trout = 572/1309 + 225/1309

= 797/1309

the probability that the next fish caught is a drum or sea trout = 0.6089
