A spinner is divided into eight equal sections. Four are shaded red and four are shaded blue with each color alternating (red, then blue, then red…). The red sections are labeled B, F, M, and T. The blue sections are labeled A, E, O, and U.

Spinning the letter B or the letter O.

Spinning red or the letter A.

Okay..i dont mind helping u..it makes me feel kinda smart..lol

Answer 14

A spinner is divided into ten equal segments. The segments are labeled with the letters A, B, E, I, L, M, O, S, T, U. Match each compound event with its probability.

Match Term Definition
Probability of A and A A) zero point one percent
Probability of vowel and consonant B) one percent
Probability of M and E and T C) twenty-five percent
Probability of a letter before J and a letter after R D) twelve percent
can u match these

Answer 15

Probability of vowel and consonant is one percent..

Answer 16

Probability of a letter before J and a letter after R is twenty five percent
Probability of M and E and T is twelve percent
and of course Probability of A ..zero point one percent

Note: For this problem, face cards and aces are not numbered cards.

thirty-six over fifty-two times thirty-five over fifty-one

thirty-six over fifty-two times thirty-five over fifty-two

thirty-six over fifty-two times thirty-six over fifty-two

thirty-six over fifty-two times thirty-six over fifty-one

Answer 24

omg, I'm sorry I didn't respond... I was not online :(
if you still need the last one ....

Number of cards: 52
Number of even cards: 4 suits x 5 numbers (2, 4, 6, 8, 10) = 20
* Face cards are only J, Q, K

Step 1: Selecting the first card w/o replacement:
Probability of even = 20 / 52

Step 2: Selecting the second card w/o replacement
Probability of even = (20-1) / (52-1)
*after step 1, there is one less even card

Total probability = Step 1 x Step 2.
