Answer:
The probability that a student earns a grade of A is 1/7.
Let E be an event and S be the sample space. The probability of E, denoted by P(E) could be computed as:
P(E) = n(E) / n(S)
As the total number of students = n(S) = 35
Students getting the grade A = n(E) = 5
So, the probability that a student earns a grade of A:
P(E) = n(E) / n(S)
= 5/35
= 1/7
Hence, the probability that a student earns a grade of A is 1/7.

Answer:
1/36
Step-by-step explanation:
6^-2
~Use negative exponent rule [ a^-b = 1/a^b ]
1/6^2
1/36
Best of Luck!
The correct answers are:
13 + 3 ÷ 3 = 1(13 + 3 ÷ 3)
13 + 3 ÷ 3 = 13 + 1
13 + 3 ÷ 3 = 13 + 3 ÷ 3 + 0
Let's look into them one by one:
13 + 3 ÷ 3 = 1(13 + 3 ÷ 3)
As anything multiplied by one will not have changes in value, this is correct.
13 + 3 ÷ 3 = 13+(3÷3) = 13 + 1
As 3÷3 is 1,this is also correct.
13 + 3 ÷ 3 = 13 + 3 ÷ 3 + 0
As anything plus zero will not have a chnage in value, this is correct.
The incorrect option:
13 + 3 ÷ 3 ≠ 16 ÷ 3
Unless there are brackets indicating addition has to be done first, devision comes before addition hence this is not correct.
Hope it helps!
