When Ilana arrives at the intersection, there's a $1/3$ chance that a light will be green.

Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Using six-sided dice, we employed each chance gadget to stimulate whether the light is red or green on a specific day. Toss in the six-sided dice and see what happens. If the number of dots on the upper side is $1$or $2$she gets a green light. If the number of dots on the upper side is $3,4,5,6$she does not get a green signal. As a result, if the number of dots on the upper side is $1$ or $2$ we know she gets a green light.

We have used each chance gadget to stimulate whether the light is red or green on a certain day using Table Do of random numbers.

Take a look at table D and pick a row.

She gets a green light if the digit is a $1,2,3$

She doesn't get a green signal if the digit is $4,5,6,7,8,9$

If the digit is zero, disregard it and proceed to the next.

As a result, we know that if the digit is a $1,2,3$she will be given the green light.

Using a standard deck of playing cards, we used the each chance gadget to simulate whether the light is red or green on a given day. Choose a card from a standard deck of cards. You have a $50/50$ chance of picking a suit from a deck of cards (hearts, diamonds, spades, or clubs) If the card has a heart symbol on it, she gets a green light. If the card has a diamond or spade sign on it, she does not obtain a green light. If the card has a club symbol on it, you must draw another card. As a result, we know that she will get a green signal if the card has a heart symbol on it.
