1 answer:
Answer: There is 16.18 inches of fabric used on a headband and 8.63 inches of fabric used on a wristband for each player.
Step-by-step explanation:
Since we have given that
Number of players = 35
Number of coaches = 2
Number of inches of fabric on headbands = 598.66 inches
Number of inches of fabric on wristbands just for the players = 302.05 inches
Length of fabric used on a head band for each player is given by
Length of fabric used on a wristband for each player is given by
Hence, there is 16.18 inches of fabric used on a headband and 8.63 inches of fabric used on a wristband for each player.

Answer: 0.82
Step-by-step explanation:
The probability of the computer not containing neither a virus nor a worm is expressed as P(∩
) , where P(
) is the probability that the event V doesn't happen and P(
) is the probability that the event W doesn't happen.
P()= 1-P(V) = 1-0.17 = 0.83
P()=1-P(W) = 1-0.05 = 0.95
Since and
aren't mutually exclusive events, then:
P(∪
) = P(
) + P(
) - P(
∩
)
Isolating the probability that interests us:
P(∩
)= P(
) + P(
) - P(
∪
)
Where P(∪
) = 1 - 0.04 = 0.96
Finally:
P(∩
) = 0.83 + 0.95 - 0.96 = 0.82
