Answer:
a. there are 22 possibilities
b. the chance of not picking red is 17/22 or 77.27%
Step-by-step explanation:
a. 6+4+5+7=22
<span>Let x=time required to mow the lawn if both work together
Then both work at the rate of 1/x lawn per min
fred works at the rate of 1/60 x
</span>Bullwinkle <span>at the rate of 1/90 x
</span>1/60 + <span>1/90 = 3/180 + 2/180 = 5/180 = 1/36
</span>
<span>rate of 1/x lawn per min so 1/36 =1/x
</span>
x= 36 min
fred mow <span>1/60 x = 1/60x36 =36/60= 9/15 of the lawn
</span><span>Bullwinkle mow 1/90 x 36 = 36/90 = 6/15 of the lawn </span>
