Deon rolled a susided die 40 times. The number 4, appears 15 times. Find the

experimental probability of rolling a 4 in the next trial

The experimental probability of rolling a 4 in the next trial is .

Step-by-step explanation:

The experimental probability is the ratio of the favorable outcomes to the total number of outcomes.

That is, the probability of an event E is:

Here,

n (E) = favorable outcomes

N = total number of outcomes

It is provided that Deon rolled a six-sided die 40 times.

And in these 40 rolls, the number 4 appeared 15 times.

A six-sided die has an equal probability of landing on any of the six numbers.

The rolling a die is an independent event experiment, i.e. the result of the previous roll does not affect the result of next roll.

Let X = number on the face of the die

Compute the probability of rolling a 4 in the next trial as follows:

P (Rolling a 4) = P (X = 4)

Thus, the experimental probability of rolling a 4 in the next trial is .

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
