Answer:

-The probability of choosing a meat dish is equal to the probability of choosing a pasta dish or a soup( $P(meat)\neq P(pasta)+P(soup)$ )

Step-by-step explanation:

Given that the number of events is 25 and 13 are meat dishes, 8 are pasta dishes, and 4 are soups.

-Probability is defined as the number of successful event divide by the total number of events.

#find probability of each event:

$P(meat)=\frac{13}{25}=0.52\\\\P(pasta)=\frac{8}{25}=0.32\\\\P(soup)=\frac{4}{25}=0.16$

$P(meat)\neq P(pasta)\neq P(soup)$

Hence, the FALSE choice is:The probability of choosing a meat dish is equal to the probability of choosing a pasta dish or a soup.
