Question

19 multiple choice 2 points if a letter is chosen at random from the word \baseball,\ what is the probability that the letter chosen is not an l? 6/8 1/8 7/8 2/8 20 multiple choice 2 points if the probability of a spinner landing on red in a game is 1/5, what is the probability of it not landing on red? 50% 80% 20% 25% 21 multiple choice 2 points mr. jones is buying a new boat. he has a choice of a canoe, a rowboat, or a kayak. each boat comes in silver or blue. which diagram shows all of the different boats from which mr. jones could choose?

Explanation:

Step1: Calculate total number of letters in "BASEBALL"

The word "BASEBALL" has 8 letters.

Step2: Count number of 'L's

There are 2 'L's in "BASEBALL".

Step3: Calculate number of non - 'L' letters

$8 - 2=6$.

Step4: Calculate probability of choosing non - 'L' letter

The probability $P=\frac{6}{8}$.

Step5: For question 20, find probability of not landing on red

The probability of landing on red is $\frac{1}{5}$. The probability of not landing on red is $1-\frac{1}{5}=\frac{4}{5}$. Converting $\frac{4}{5}$ to percentage, $\frac{4}{5}\times100\% = 80\%$.

Step6: For question 21, analyze the choices

Mr. Jones has 3 types of boats (canoe, rowboat, kayak) and each boat has 2 color options (silver, blue). The correct tree - diagram should branch out from each boat type to the two color options. The given diagram for canoe is wrong as it branches to kayak instead of color options for canoe. The correct way to represent all choices is to have three main branches for canoe, rowboat and kayak, and from each of these branches, two sub - branches for silver and blue. But since no correct diagram options are fully shown in the problem statement, we assume we are just checking the concept of branching for each boat type to color options.

Answer:

1. $\frac{6}{8}$
2. 80%
3. (No correct diagram fully shown, but concept is to have 3 main branches for boat types and 2 sub - branches for colors from each main branch)
