A mechanical dart thrower throws darts independently each time, with probability 10% of hitting the bullseye in each attempt. Th

Arturiano [62]

Answer:

The probability of hitting the bullseye at least once in 6 attempts is 0.469.

Step-by-step explanation:

It is given that a mechanical dart thrower throws darts independently each time, with probability 10% of hitting the bullseye in each attempt.

The probability of hitting bullseye in each attempt, p = 0.10

The probability of not hitting bullseye in each attempt, q = 1-p = 1-0.10 = 0.90

Let x be the event of hitting the bullseye.

We need to find the probability of hitting the bullseye at least once in 6 attempts.

$P(x\geq 1)=1-P(x=0)$ .... (1)

According to binomial expression

$P(x=r)=^nC_rp^rq^{n-r}$

where, n is total attempts, r is number of outcomes, p is probability of success and q is probability of failure.

The probability that the dart thrower not hits the bullseye in 6 attempts is

$P(x=0)=^6C_0(0.10)^0(0.90)^{6-0}$

$P(x=0)=0.531441$

Substitute the value of P(x=0) in (1).

$P(x\geq 1)=1-0.531441$

$P(x\geq 1)=0.468559$

$P(x\geq 1)\approx 0.469$

Therefore the probability of hitting the bullseye at least once in 6 attempts is 0.469.

At a display booth at an amusement park, every visitor gets a gift bag. Some

kotegsom [21]

The bag will often contain all three items every 70 bags ⇒ answer C

Step-by-step explanation:

At a display booth at an amusement park, every visitor gets a gift bag

according to these information:

1. Hat Every 2nd visitor

2. T-shirt Every 7th visitor

3. Backpack Every 10th visitor

We need to know how often a bag will contain all three items

To solve this problem you must find a number divisible by 2, 7, and 10

To find that number start with the multiples of the largest one and

check them with the other two numbers

∵ The largest number is 10

∵ The multiples of 10 are 10 , 20 , 30 , 40 , 50 , 60 , 70 , 80 , .......

- Look for the first multiple of 10 is divisible by 7

∵ 70 is the first multiple of 10 divisible by 7

∵ 70 is divisible by 2 because its even number

∴ 70 is the smallest number divisible by 2, 7 and 10

The bag will often contain all three items every 70 bags
