Answer
### Explanation:
## Step1: Calculate total number of envelopes
$1 + 2+3 + 3=9$
## Step2: Calculate number of green or yellow envelopes
$3+3 = 6$
## Step3: Calculate probability
The probability $P$ of selecting a green or yellow envelope is the number of green or yellow envelopes divided by the total number of envelopes. So $P=\frac{6}{9}=\frac{2}{3}$
### Answer:
$2/3$
### Explanation for second - part:
## Step1: Recall the Celsius - Fahrenheit conversion formula
The formula to convert Celsius ($C$) to Fahrenheit ($F$) is $F=\frac{9}{5}C + 32$.
## Step2: Substitute the value of $C$
Given $C = 38.3$, then $F=\frac{9}{5}\times38.3+32$.
First, calculate $\frac{9}{5}\times38.3=9\times7.66 = 68.94$.
Then, $F=68.94 + 32=100.94$
### Answer:
$100.94$
