Probability is the chance of an event occuring. It is obtained by the formula number of outcomes / total number of possible outcomes.
The probability of a blue jay being the next bird papa sees is given by number of blue jays / total number of birds = 59 / (59 + 68 + 12 + 1) = 59 / 140 = 0.4214

A total of 399 tickets were sold for the school play. They were either adult tickets or student tickets. The number of students
weqwewe [10]

133 adult tickets were sold.

Step-by-step explanation:

Given,

Total tickets sold for school play = 399

Let,

x represent the number of children tickets sold.

y represent the number of adult tickets sold.

According to given statement;

x+y=399      Eqn 1

x = 2y           Eqn 2

Putting value of x from Eqn 2 in Eqn 1

2y+y=399\\3y=399

Dividing both sides by 3

\frac{3y}{3}=\frac{399}{3}\\y=133

133 adult tickets were sold.
