a six sided number cube has faces with the numbers 1 through 6 marked on them. what is the probability that a number less than 2

Solution:
we are given that
A six sided number cube has faces with the numbers 1 through 6 marked on them.
we have been asked to find the probability that a number less than 2 will occur on one toss of the number cube.
Since a number less than 2 is only one and that is "1" and total number of possible outcome is 6.
and as we know that probability is given using the formula
Substitute the values we get
Hence the required probability is 1/6.

Answer: The two answers are 1.08<em>T</em> and (1 + )<em>T</em>.
Step-by-step explanation:
Try multiplying 1.08 times any random number. If you use 5, 1.08 times 5 gives you 5.4. This makes sense. Solve the other other expression as well and substitute <em>T</em><em> </em> with the SAME number that you used before (5). Hope that helps!
Answer:
A - The proportion of students that like trance music but not dubstep is 10%
B - The proportion of students that like either dubstep or trance is 40%
C - The proportion of students that like neither trance music nor dubstep is 60%
D - The proportion of students that didn’t select any of the music options available on the survey was 40%
E - The proportion of students that preferred either dubstep or trance is calculated by: P(D) + P(T) - P(D and T)
F - The conditional probability that a student likes dubstep, given that he or she likes trance music, is 60%
Step-by-step explanation:
P(D)=the students preferred dubstep=30%
P(T)=the students selected trance music=25%
P(H)=the students selected house music=20%
P(D and T)=the students liked both dubstep and trance=15%
<em><u>A - The proportion of students that like trance music but not dubstep is:</u></em>
P(T) - P(D and T)=25%-15%=10%
<u><em>B - The proportion of students that like either dubstep or trance is:</em></u>
P(D) + P(T) - P(D and T) =30%+25%-15% = 40%
<u><em>C - The proportion of students that like neither trance music nor dubstep is</em></u>
100% - (P(D) + P(T) - P(D and T) ) =60%
<u><em>D - The proportion of students that didn’t select any of the music options available on the survey was:</em></u>
100% - (P(H)+P(D) + P(T) - P(D and T) ) =40%
<u><em>F - The conditional probability that a student likes dubstep, given that he or she likes trance music, is:</em></u>
