Respuesta :
A jar contains 5 blue marbles, 8 red marbles, 4 white marbles, and 3 purple marbles.
Number of blue marbles = 5
Number of red marbles = 8
Number of white marbles = 4
Number of purple marbles = 3
Total number of marbles = 5 + 8 + 4 + 3
Total number of marbles =20
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes
[tex]\text{ Probability = }\frac{Number\text{ of favourable Outcomes}}{Number\text{ of Possible Outcomes}}[/tex]Probability of picking white marbles + Probability of not picking marbles = 1
Probability of not picking white marbles = 1 - Probability of picking marbles
[tex]\begin{gathered} \text{ Probability of picking white marbles = }\frac{Number\text{ of white marbles}}{Total\text{ number of white marbles}} \\ \text{ Probability of picking white marbles =}\frac{4}{20} \\ \text{ Probability of picking white marbles =}\frac{1}{5} \\ \text{ Probability of picking white marbles =}0.2 \end{gathered}[/tex]As :
Probability of not picking white marbles = 1 - Probability of picking marbles
Probability of not picking white marbles = 1 - 0.2
Probability of not picking white marbles = 0.8
Answer : Probability of not picking white marbles = 0.8
Answer:
4/5
Step-by-step explanation:
5 blue marbles, 8 red marbles, 4 white marbles, and 3 purple marbles = 20 marbles
not white marbles = 5 blue marbles, 8 red marble and 3 purple marbles = 16 marbles
experimental probability
P ( not white) = note white ) / total = 16/20 = 4/5
