Question

if you choose the answer to this question at random what is the chance you will be correct
a 25%
b 50%
c 0 %
d 79%

Answer 1

★ To FinD :

We jave to find the chances (probablity) that my answer is correct.

$\rule{200}{1}$

★ ExplanatioN :

→ Total outcomes = 4 (because there are only 4 options and 4 cases of getting the answer correct.)

→ Favorable outcomes = 1 (because out of the 4 cases only 1 case would be correct.)

We know the formula to find the probablity when total outcomes and favorable outcomes are given.

$\large{\implies{\boxed{\boxed{\sf{Probability = \frac{Favorable \: outcomes}{Total \: outcomes}}}}}}$

★ Putting Values ★

$\sf{\dashrightarrow Probability = \frac{1}{4}} \\ \\ \sf{\dashrightarrow Probability = 0.25}$

$\rule{150}{2}$

Now,

We will convert it into percentage by multiplying it by 100.

→ Chances = 0.25 * 100

→ Chances = 25%

$\large{\implies{\boxed{\boxed{\sf{Chances = 25 \%}}}}}$

$\therefore$ Option A is correct.

Answer 2

Answer:

To FinD :

We jave to find the chances (probablity) that my answer is correct.

★ ExplanatioN :

→ Total outcomes = 4 (because there are only 4 options and 4 cases of getting the answer correct.)

→ Favorable outcomes = 1 (because out of the 4 cases only 1 case would be correct.)

We know the formula to find the probablity when total outcomes and favorable outcomes are given.

\large{\implies{\boxed{\boxed{\sf{Probability = \frac{Favorable \: outcomes}{Total \: outcomes}}}}}}⟹

Probability=

Totaloutcomes

Favorableoutcomes

★ Putting Values ★

⇢Probability= 4/1

⇢Probability=0.25

Now,

We will convert it into percentage by multiplying it by 100.

→ Chances = 0.25 * 100

→ Chances = 25%
