The number cube is rolled and a coin is tossed .How can you sketch a tree diagram to represent the sample space ?

Refer to the diagram in the attachment.

Step-by-step explanation:

There are two events here: the first one is the number on the cube. The second one is the outcome of the coin toss. This tree should contain two columns, one for each event.

Start with the first column. Let be the outcome of the number cube. There are six possible values: . That corresponds to six branches, one for each outcome.

Continue to the second column. Let be the outcome of the coin toss. No matter which number was obtained for , there would always be two possible outcomes for

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
