The probability being fixed at 1/3, let's find which event in rolling a 6 sided dye will generate a probability of 1/3.
A- 6 sided number cube: with one roll (INCORRECT), however with a 3 sided number cube, P(0ne roll) = 1/3 (CORRECT)
B- A roll of an even number : P(even number) =3/6 =1/2 (INCORRECT), and a roll of an odd number P(odd number) = 3/6 = 1/2 (INCORRECT)
C- A roll of a number less than 3 , P(less than 3) =2/6 =1/3 CORRECT), whereas :a roll greater than or equal to 3. INCORRECT
D. A roll of a number that is not divisible by 3, P(not divisible by 3) = 4/6 =2/3 (INCORRECT): P( number number that is divisible by 3) =2/6 1/3 CORRECT
Answer:
A and E
Step-by-step explanation:
x² = 81
~Take the square root of both sides
x = ±9
Best of Luck!
Sum of all the angles in a triangle is 180°.
Therefore in ΔQRS,
R + S +Q = 180°
61° + 29° + Q = 180°
Q = 180 - 61 -29
Q = 90°
Hence option A is correct.
Hope this helps, have a nice day!
